Why does everyone tailgate me?

drive so fast? I see big Suvs tailgating people all day and driving so fast. The speed limit here is 60 and people are always going 70. Everyone always tailgates me and they can't wait to fly around me. What is the hurry?? I go 45 in the right hand lane, the minimum and everyone flies around me so fast. I am 20 years old so the way I look at it is like bring it young buck or gal because I am your age if not younger. I always get cut off right away or just people rum their motors up as they go by. Its so stupid. I am fighting for equal rights on the highway for us minimum speed drivers. Elderly people might get nervous, but I got their back I am 20 and get tailgated so its alright. hahaha :-) But why is traffic always in such a hurry? Everyone is always hurry hurry hurry. My mom said life has changed a lot since she was growing up as far as the hurrying goes.
