Is it alright that I keep a list of license plate numbers of cars that drive badly.
Have you tried talking to the drivers of the cars about how badly they drive?
No, they drive so badly that is not worth it.
I understand being frustrated and annoyed by bad drivers since they can cause accidents. However, collecting their license plate numbers is not going to help and may cause people to suspect you of something more sinister if they see you writing down plate numbers.
I can't stand bad drivers.
It's completely normal to be annoyed with bad drivers, but you can't make all the bad drivers in the world suddenly be good drivers. Instead of focusing so much on bad drivers, it's best to just be extra careful when driving and focus more on yourself.
