Just like to ask the rest of the tsikot members, What are the things that irritate you the most with drivers or cars with bad etiquette?

For those who are adding just copy and paste the itemized list.
Thanks

1. Not turning on the head lights when it is already dark. Especially the taxis, jeeps and motorcycles. - Nagtitipid ba sila sa bumbilya?
2. Brand new cars/SUV etc who don't know how to use their signal light.
