I say this whenever this topic comes up: we have public transport today, it's safer and cheaper than having a car, it allows you to make use of your commute time (read, study, eat a sandwich, have a coffee), it's better for the environment (electric doesn't come from nowhere), and it's faster and even more so if more people use it. Your city maybe lacks it, but then the solution is not to say "meh, public transport is crap" and go buy a car. But this is the answer I always get in this community of people who make a living finding solutions to problems.
On the road, an actor's actions do not merely affect itself, but all the others on that road. If you slow down at a point, that can cause the driver arriving at that point five, ten minutes after to stop. On the road, everything creates a butterfly effect. And just like you can't run around naked or listen to very loud music in residential areas, you can't just get on the road with your new toy which if fails, does not only put your life at danger, but also many others'.
