Its just the fact that you know about 240's and ka's and sr's and what people are doing with them thats why you see a lot of them on the road.
Now if you didnt know about 240's and you drove a ford escort every day you wont even notice the 240's but you will notice that there is a lot of ford escorts on the road. I know people that drive civics that dont even know what a 240 is but as soon as another civic passes by they point at it and say did you see that civic and I reply no but I did see that 240 that passed the other way.
