I have to disagree. My daily driver (Acura TL) will accelerate well beyond the speed limit by just "resting" my foot on the pedal. Some cars do it naturally without even trying, turbo cars are especially known for this. Same thing with high end luxury cars being so smooth at high speeds. They feel the exact same at 140km/h as they do at 120km/h, whereas an old Kia will start bouncing coins off the dashboard to let you know.
Sometimes it really isn't on purpose.
When I went to ask for a reduction on a speeding ticket about 6 or 8 years ago I sat in court for a few hours listening to people try that flavor of excuse over and over again. The judge just repeatedly asked them if their vehicle was suffering any mechanical problems that caused the brakes to be non functional, and if so, their vehicle was to have it's licence plates pulled off immediately. Not surprisingly nobody answered yes. Then he asked if the driver was suffering any medical issues that prevented them from being mentally cognizant of their speed, and able to read the speedometer. He indicated that if they had such problems that their licence would be
immediately suspended until they were able to receive medical clearance. Not surprisingly nobody answered yes to that either.
Then he basically said, "So what's your excuse?", and most people just sat there with their tails between their legs and the charges stood. And when you fight a ticket and loose, you are no longer eligible for any dollar or points discounts, so they paid the full hit.
And I agree. If you are not fully cognizant of your vehicle 100% of the time you are lacking a pretty important driving skill.
And yes, before someone mentions it, I was indeed fighting a speeding ticket for doing exactly that - having my 145,000# truck accelerate down a hill and through a speed trap. 91KPH in an 80 zone..and I WAS aware of it and I WAS on the brakes and the jake- had I not been I would have easily been doing 120+ given the weight and the hill. I remember it well, the OPP officer had a bug in his *** for big trucks basically. Still technically my fault though, I owned it, but the judge kind of wrinkled his nose at the pettiness of it and knocked it down to no points and something like a $30 fine, I forget exactly what the details were.
