Write about something you hate.
I hate motorized scooters. I live in London and over the last few years, they have become extremely popular for people getting around the city. Most people are okay on them, but there are far too many who will go too fast, and ride on the pavement. I've been crashed into a few times and I have read news reports of people being seriously injured and killed by them. 

The rental scooters can often be left abandoned on the pavement or in parking spots, creating an eyesore and a hazard. They should be regulated better!
