Can you think of some reasons why you should not enter in such programs?
I have a friend who is likely to buy a car soon, and is very enthusiastic towards such a business. Besides the fact that maybe it wrecks the look of your car a bit, can you think of a reason not to do this?

No I can't but I have tried and it's very hard to get into. They want you to drive a lot of miles everyday. Which is understandable.

If you can't meet qualifications and requirements then you probably should not join one. If it's some sort of legal issue you are worried about than maybe you should read their TOS. I'd like to say you should be fine. (If you can get in) But I can't. So your best bet is to do as much research on them as you need.

I don'r konw about this
