Why am I promoting Electronic Stability Control?  I have no financial interest in ESC.  Yet I spent thousands of hours over the last two years trying to raise awareness.  Here is my story.

In October, 2005, my good friend Annie, a teacher from Smithers came to Prince George in search of a new car.  She was commuting daily to her job in Houston, sharing the road with giant transport trucks, and she was constantly afraid that she might lose control and die.  She said she needed four-wheel-drive (“4WD”) to stay in control.

I told her 4WD won’t help her stay on the road.  It might help her out of the ditch but it won’t improve cornering or braking.  I took her to my Volkswagen dealer and we took a new Golf out for a test drive. 

We went to Shelley Road which snakes through a farmer’s field.  The twisty road was covered in compact snow and ice.  Annie drove the car through the curves as speeds that were frightening.  I said, “Slow down, you’re going to put this car in the ditch, and I’m going to be embarrassed with the dealer.” 

She replied, “It’s no problem.  It’s handling fine.”  I took the wheel and found that Annie was right.  It hugged the road better than any car I had ever driven. 

We returned to the dealer and asked, “What’s with this car?”  The dealer explained how Electronic Stability Control helps the driver maintain control.  I got curious and started researching ESC and what I found was amazing. 

Studies worldwide show that ESC profoundly reduces crashes and save lives.  However, the public was unaware of ESC.  In early 2006, a survey by Transport Canada revealed that only one percent of Canadians named ESC as a safety device. 

Northerners know the dangers of moose on our highways.  ESC was invented because of moose.  ESC was conceived by Mercedes in 1959.  However, it stayed on the drawing board until 1995, when cars were being driven through a "Moose Test."  This means swerving around an imaginary animal on the road. 

During the Moose Test, a journalist jerked the steering wheel violently and rolled a Mercedes A-class car.  The same day, an East German economy car called the Trabant navigated the Moose Test without incident.

Reporters were amused, but Mercedes was not.  Mercedes recalled 130,000 cars and installed ESC for the first time in production cars.  Within three years, Mercedes enjoyed a 21% reduction in driver-related crashes and four years later, that figure reached 42%.  Other auto makers took notice and started installing ESC in high-end cars.  Then traffic experts around the world started to notice the amazing benefits of ESC.

It is tragic to lose young soldiers in Afghanistan.  To date, more than 70 young Canadians have died there.  Yet in that same time period, nearly 15,000 Canadians have died on our highways.  Many Canadians accept highway fatalities as the inevitable price of mobility.  I do not.  ESC could prevent up to 43% of road fatalities and thousands of debilitating injuries.

Graeme Johnstone, Chief Coroner of Victoria, Australia called on all car manufacturers and importers in Australia to make ESC standard, calling it "technology we must have."  I agree.  I bought a car with ESC. 

Last week, I took my car to an icy parking lot and tried to lose control.  Results were more impressive than I expected.  I phoned Ben Meisner and invited him for a test drive.  Watch this space; you’ll soon read about it.

I wrote several letters and sent research reports to the BC Coroners Service, asking them to make a public statement on the role ESC would play in reducing crashes here at home.  Last week I invited Shane DeMeyer, Regional Coroner to take my car for a “spin” in the parking lot. 

Mr. DeMeyer is well-informed about cars.  He hasn’t yet accepted my invitation, but he wrote, “Thanks Glen.  As we have discussed in the past, I do agree with you about the efficacy of ESC.”

Last Monday, a car lost control on Highway 16 near Cluculz Lake, spinning into a transport truck and killing a mother and four children.  I have now invited Mr. DeMeyer to drive my car at the accident scene.  I will let you know his response.

I now call again on the BC Coroners service to inform the public about the role ESC would play in reducing fatalities and making British Columbia highways safer for mothers and children such as those who died near Cluculz Lake.

Glen Nicholson is an independent safety advocate.  This is the second in a series on ESC.  For more information, including video links showing how ESC works in the Moose Test, look up “Electronic Stability Control” on Wikipedia at this link:

Sounds good, another feature so motorist don't need to slow down. Yes don't slow down to road conditions just use those features the car manufactures put on their vehicles because time is to important to slow down. Then blame everyone but yourself for your accident. Yes the road maintenance contractor is maintaining the road poorly, yes use that one. I think a beter feature is a IQ meter in the car, and then the vehicle responds accordingly.
Hmm, seems to me you don't have to be going fast to die in a car crash. Reminds me of two older ladies, who were obviously tempting fate by travelling at breakneck speed, spun on horrid road conditions and just missed a chip truck, luckily because that was my mother. Perhaps ESC is an answer, whether in sleet, snow or just playing slalom with moose and deer, any safety device that saves lives should be implemented. Road crews cannot be everywhere at once and we still need mobility. Not everyone is a professional rally driver like myself, so i'd feel a tad more comfortable knowing the car coming head on was equipped with ESC.

Someone help me!! Can i get ESC installed after market on an older vehicle?
Unfortunately, ESC is not available for after-market installation. It is available from all car makers as standard or optional equipment in about 37% of all new cars, trucks, and SUV's.
"Last Monday, a car lost control on Highway 16 near Cluculz Lake, spinning into a transport truck and killing a mother and four children. I have now invited Mr. DeMeyer to drive my car at the accident scene. I will let you know his response."

Good Lord!!!! Same speed? Same road conditions? Truck coming on? Car overloaded with passengers? Likely distractions? Possible panic to get to an appointment on time?

And you are going to ask someone to replicate that? And you are an safety advocate?

I think these words from the TC site need repeating here:

"As is the case with many safety features, they can lead to a false sense of safety among some drivers. This technology does not and cannot change the laws of physics.

Even if your vehicle is equipped with ESC, you must continue to drive prudently. If you drive too fast for the specific set of road conditions, you can still lose control even with ESC.

Good tire and brake maintenance are equally important for safety. The best ESC system can do little to assist you if your tires are worn-out, under-inflated or overloaded."
Owl is right about good tires. ESC does not increase grip. ESC helps drivers take advantage of the available traction by reacting faster than humans can. Proper winter tires combined with ESC make driving much safer on our current slippery roads.
Owl is not right in suggesting that I would expose the coroner to needless risks. After ensuring that the scene is safe, he could drive the same route with ESC and proper snow tires.
Seen a guy in a company truck "pump" his anti-lock brakes all the way down Peden Hill. What a maroon. Too bad they don't sell IQs.
"After ensuring that the scene is safe"

?????????

As in non glazed roads?????

As in no traffic? .... gonna set up cones???

As in not going over the speed limit, let alone going over a speed suitable for the conditions.

This system works when one is driving purdently in relatively ideal road grip conditions and is confronted with a sudden change in the conditions such as an animal crossing the road. The tendency is to swerve to try to avoid the animal which could cause a vehicle with a high centre of gravity, such as an SUV to overturn. In fact, I had that sort of accident in a low car many years ago to avoid a deer. Being a low sports car it skidded (in the summer) but did not overturn until I ended up close to a very steep ditch when the car was virtually stopped and ended up on its roof.

I suspect that an ESC system on the car at the time would have ended up with better control of the car.

Of course, remember that if one has to swerve in such a situation and the system tend ot keep the inertia of the car going in the same direction that it was heading in, you will have a hard time to try to avoid the animal. So, you hit the mooose instead. And we all know what happens all too often to the car and its occupant(s) when one hits a moose straight on.
"Seen a guy in a company truck "pump" his anti-lock brakes all the way down Peden Hill."

Too many people who have automatics do not realize that in those situations they should be be using the lower gear of the automatic to use the engines as braking power. Instead they burn up their brakes.

When I travel down University hill I do not use any brakes till I hit the bottom and have to stop at the light. Too many others use their brakes for much of the way.
Give me a vehicle with ESC, good tires and great handling and I'll take that any day of the week over surrounding myself with 5,000 pounds of steel and 4WD.

Common sense obviously still applies when driving ANY vehicle, however, I'd prefer to have a vehicle with a better chance of avoiding an accident than barreling down the road in a lumbering truck or SUV. Don't get me wrong, I love my 1/2 ton, but it also has pretty major limitations in other areas.
Ive got ESC, Not installed in my vehicle but in my brain! Its the electronic impulse from my brain to my foot that tells me to take my foot off the gas when the roads are shitty.
You also need four feet, four brake pedals, and super-human reflexes to keep up with ESC.
Harbinger, Owl, and Northman raise interesting points about brakes, gears, and gas.
Readers should know that:
- ABS brakes do their own high-speed pumping, releasing the brakes many times each second to help drives maintain steering control. You should not manually pump ABS brakes. Instead, apply steady foot pressure and let the electronics work for you.
- Suddenly lifting you foot off the gas or suddenly gearing down can be dangerous in front-wheel drive vehicles, especially travelling downhill into a slippery curve because the engine will slow your front end while the back end tries to spin the vehicle around.
ESC works with ABS to maintain your intended direction, allowing you to brake, gear down, or lift the gas pedal under control.
