I think the TV channels and sponsors could create public service announcements around this issue to raise awareness. If we can't control our drivers, be it for how they are parking or the way they are driving, we are constantly creating risk and nuisance, both of which should be things avoided in a 'civil society'.
The bus drivers are harder to get to, who probably get away with the most serious offenses. Apart from ensuring great penalties on the owners of bus services for these offenses - from damaging public property (road dividers, pavements, etc.), to minor assaults (bumping into other cars, buses and people), to killing; we should take steps to have them view some sort of mandatory educational material as part of their license test. Those should clearly outline the damage they can cause when someone dies or loses a limb due to their callous driving.
I have found a few public announcement videos that have been created in New Zealand to caution drivers. The first uses animation to show the effect of selfish driving and how being social can help you have a better day. The second and third are graver, and shows how split second decisions can lead to an unwanted situation.
