Here we go. Yes, there are people who behave badly on the roads, whether they're cycling or driving. They probably behave badly when they're not engaged in the process of transporting themselves. You'll probably find they put their feet on the seats when on the train and play loud music on the bus. I had a car nearly take me out the other day as I crossed the road. she careered round a corner at speed, without a care. I see cyclists ignoring lights and regularly see cars breaking the speed limit as well as jumping lights. It's not helpful to make this into a 'bike versus car' thing. What would help is if we actually had traffic police back, rather then just putting speed bumps everywhere and thinking that solves anything.
