No, BC is definitely not safe.  I saw a wonderful scene in walmart the other day, a pair of hammies using mobility scooters.  They lady of the couple was having a difficult time steering away from the shopping carts and kept hitting them.  While the fat male watched in with a look of condescending amusement.  It shocked me cause they guy was too fat and lazy to walk to do his Walmart shopping..yet was that he could at least drive a fatcart, ha!  Well done you?!
