Aviation is a great example of how a culture of safety can be built up. Driving culture in the US is markedly different. It's absolutely normalized to overtake a slow moving vehicle even when it's not safe and passing conditions are unclear, to be distracted and use your phone, to drive drunk, to drive along the shoulder of a crowded highway if you're in a hurry, to double park in an urban area if you "just need to stop and pick something up". The enforcement aspect is just the lagging edge of that. Hearing people talk, you'll casually hear "oh I accidentally bumped the car next to me in the parking lot while parking oops, I just reparked somewhere else." It shows; the US has the highest car crash incidence among developed nations by a long shot, with Canada a distant 2nd place.

The reason the US is considered a driving culture is only partially legislation and only partly infrastructure, it's due to a culture that treats driving as a loosely enforced activity where faults should be given the benefit of the doubt. This is the opposite of aviation where safety is emphasized in every part of the process and scary moments are encouraged to be reported anonymously through ASOS. Infrastructure is stressed as the ideal solution because it involves very little cultural change but due to a reluctance to raise taxes and aforementioned driving culture, people resist infrastructural changes which help non-drivers.
