My brother was riding a bike back from a bar a couple of weeks ago, hit a curb, went ass over teakettle into the ground and broke his face. Nose, teeth, scraped the skin off half his face, landed in an ant bed and got over 300 ant bites plus knocking himself out for over 5 minutes. That earned him an ambulance ride and a lovely expensive CT scan to make sure he didn’t break his head too.
Walking isn’t that safe either, but I think its the best option. For the drinker, driving is less risky than cycling and far more risky than walking.
