Is driver's-side-only door really safe?

I am wondering about the number of TearDrops I have seen that ONLY have a door on the street (driver's) side. It seems to me this might be unsafe for loading and unloading on a busy street.
Also, most campgrounds that have concrete pads are set up for the door being on the passenger side. I think when I build mine, I would like to have BOTH doors, for safety and also, when my bride is with me, we don't have to crawl over each other to get in or out. Any ideas?
