Suppose I were travelling at 12mph on a bike when I was rear-ended by a car travelling 40mph. Would that be fatal? What if the car were going 30mph or 50mph?
I'm an engineering student. I live two miles from campus. I own a car. I'll drive it if I have to, but I'd rather be cycling.
The proposed route is one mile along a two-lane road with 40mph traffic and a "bicycle lane" which is basically a wide shoulder with a paralellogram painted on it, then one mile down the same road with the same bike lane after it widens to four lanes and speeds up to 55mph traffic (speed limit 45). I consider the chance of being hit to be slim, but the consequences of such a collision are quite unknown to me.
