Why do people try to race my car? Is it a bad thing?

I have a 1999 red honda civic ex coupe with black and chrome rims. Everything is pretty much stock. Im not into jucing up or suping up cars to make them faster because its just my work car and car i drive to college. But i was at a red light and this white audi car pulled up beside me it looked like it could be a 2015 audi tt with red rims but they kept horsing their motor at me so when the light turn green i took off and they caught up with me and kept horsing their motor and it seemed like they suped up their car because the way it sounded like it was a boom of thunder lol but it was so loud that it rattled my car. I was scared because we was in the city limit and the speed limit was 35 mph. I wasnt trying to race them but they passed me and they kept slowing down i guess waiting for me to catch up to them but i just kept driving slow so they just took off and left. Im not the type of person eho race or show off but does that make me look bad and scary?
