The article did say that there were witnesses, though. They detained the guy.
I've ridden in that area quite a bit. It can get really busy with traffic. I'll ride up Crown Valley or Thalia and Park to Top of the World. Because of incidents like this I don't enjoy riding on the roads as much as I used to. People are too preoccupied on their phones or whatever and not attentive to driving. I has gotten much worse in the last 10-15 years.
My guess is that there was some road rage involved. The driver probably cut off the cyclist/victim or got too close to him in some way and the cyclist flipped him the bird, yelled profanities at him, or whatever. The driver then freaked out. I used to do the same thing when I was younger but as I got older I wised up and decided it just wasn't worth it. A 180 pound guy on a 20-25 pound bike doesn't have a prayer against an enraged guy in a 2+ vehicle. The article said that the victim was 58. That is older than I am. If that is what happened I would have thought that the victim would have known better. I hope that the driver is made an example of.
I would personally NEVER ride where there is a lot of traffic...or really ANY traffic. Too many a$holes who don't think bicycles belong on roads. Too many distracted or impaired drivers. Too many just bad drivers. I think it is foolish to ignore those realities. Also, why exercise where there is a lot of car exhaust?
That said, the driver in THIS story is out of his freakin' mind.
Biking is not only for exercise. So.e people do not own a car, it is their transportation. This guy was commuting home from work. Having to drive less than 2 miles is just a sad state in USA of car dependancy
