This is what we saw driving along the Coquihalla Highway in Canada, a rather infamous stretch of road featured on the Discovery Channel, and yes, we saw a number of cars and trucks off the side of the road, and not in a good way

The road was iced over in place, and driving was difficult, but on the plus side the scenery was spectacular, and it was hard not to be distracted when driving.
But, inspiration for a story? It might go something like this:
…
Arty was adamant that he knew the best where man in the business.
That might gave been true if he was in the middle of the city where there were endless tests and turns that could be used to lost chasing police vehicles.
But that didn’t apply to the open road, and one that was think with ice and snow, even if it had recently been cleared.
But that wasn’t as bad as the fact that we had got free of the city, lost the pursuing cars, changed vehicles, and got away free.
All he had to fo was follow the road.
Except Arty had a temper, and getting stuck behind an old van going ever so slowly on the road, caused him to first blast them with horn, then start doing dangerous accelations up behind them, and then attempt to overtake on a bend in the road.
That might not have been so bad if there had not been an oncoming car, but there was.
Even that might not have been so bad if the car had not been a police vehicle.
But the real kicker: Arty lost control of the car and we went sailing off the edge of the road into a ravine, landing on soft ice which after a minute started cracking and then gave way.
The last place I wanted to be was to be sinking into a freezing cold river, but there we were, all frantically trying to get out.
Fortunately, I did, but not before I was soaking wet, and almost frozen. The rest didn’t make it.
