Ya i have a few of these so called witnesses living on my street. I would drive my camaro with a loud exhaust in first gear slowly accelerating as they run out of their house waving their hands and yelling at me to slow down... as i peak down at my speedometer and notice im doing 20 km/h in a 50 zone hahaha
These same "witnesses" will hear a bike accelerate from 40-80 km hard in 1st gear and will swear the bike was doing atleast 200km/h...
But that's not at issue here. What's at issue is a crash with physical evidence in the form of damaged vehicles, debris, fluid, and skid trails on the road surface, and so on. So let's get back to the question that you haven't answered with respect to the Dixon Rd crash:
Exhaust noise didn't move that car to where it landed.then what caused the car to suddenly change direction and literally jump sideways to land 20 to 25 feet away from where it was hit? Do you think a little low-speed love tap would cause that 400-pound bike to make that sort of impression on 3400 pounds worth of car and driver?
