They should make everyone looking to get a driving licence take a cycling proficiency test (including some town centre road miles before hand. Perhaps then when they got behind the wheel they might have a better idea of the consequences.
That’s the catch22 situation that the UK is now in, it’s seen as too dangerous to cycle because of traffic so nobody (or very few)does, because there is so few cyclists there is no proper infrastructure.
Cycle racks have gone from most schools a long time ago, so a lot of kids are now growing up and becoming drivers without ever ridden a bike.
That’s the thing about country’s like the Netherlands and here in Germany, lots of people cycle at least occasionally, kids ride bikes to schools, lots of people cycle to work in summer. So even if someone doesn’t cycle themselves, there is a very good chance there children or other family members or friends do. So it makes a lot of people far more aware of cyclists, still get the odd nobhead, but generally most drivers are far more respectful of cyclists.
