> How about the percentage of bad drivers vs bad cyclists? I see a lot of bad drivers because they're more drivers. I'd guess about 1 in 40 cars I see are doing something illegal and unsafe. I'd say I see 1 in 10 bicyclists doing something illegal and unsafe.
Collected data disagrees with you. Strongly suggesting you’re falling prey to confirmation bias, or you’ve become highly desensitised to driver misbehaviour. Neither of which would be surprising if you live and drive in the US (my experience of driving in the US, is that it’s almost designed to make it hard to do the right thing as a driver, little to know affordances in the infrastructure to allow for normal human error).
> Just curious... Do you have asource for your data though? Google seems to indicate that cyclists and drivers are similar in their law breaking.
I assume these conclusions change by locality, and collections method. However I’ve never seen a study demonstrate that cyclists break the law substantially more than drivers. Certainly nothing close to the 4:1 ratio you suggest.
> I'd love to find data like this for the US. If your Google-Fu is better, can you source me some?
I don’t have any US data unfortunately, I’m mostly interested in the UK where I live.
Ultimately the TL;DR is that cyclists are no worse at rule breaking than drivers. They just tend to break different rules, and driver rule breaking is almost entirely normalised. Big difference of course is severity of outcome, which pedestrian fatality rates suggest is about 400x to 1000x greater when a car is involved.
If drivers really cared about the safety of road users, they be up in arms about poor driving standards, and the lack of consequences for drivers that kill people. They wouldn’t be shouting about cyclists.
