We did that to an old station wagon once and called it a "fair weather ride". Now, I would just call it stupid. No offense.
If you did this at all, I would make the doors to where they could not open and hide some sort of support in there. Then you would have to climb over the doors to get in and out, otherwise, like stated.. Do not do this, that is unless there is no value to your life.. and if so.. just buy a bike.
