When I was growing up in the UK, Department for Transport or whomever always had TV and radio ads reminding people how to drive: take longer to look for bikes, don't hang out next to a big lorry (truck) blind spot, don't drink and drive, it's hard to focus on two things at once so put your phone away while driving, etc. And they still do this. We need more of that elsewhere too.
