Carmakers should not market cars that don't comfortably fit into standard parking spots.
Yes yuppie lady, I saw the evil looks you gave me when my son gently bumped your car with his door. You checked it - there was no mark there. I did also notice the scrape on my car door when I got back. You'd left already. I wonder if you noticed that one?

I'm not sure about other states, but it is illegal to smoke within x metres (can't remember) of a playground.

When driving on the open road and unable to reach speeds anywhere near the limit, pull over when you get a chance to do it safely and let the 10 cars behind you go through. Some truckies are great about doing this, really appreciate it. The old fogies/directionally challenged are not.
