while sitting on the motorcycle why are girls put there both legs in same side.?

because if your wearing a skirt or dress you have to keep your keens together

No, not unless they run then the appendages on the same side work in tandem. When walking, they are like humans and must counterbalance themselves. that means as they push off their left hind foot their right forefoot must reach forward. They may have a lower center of gravity than humans, but they still need to maintain it.

i guess they want to look sexah but fails from falling off the motorcycle. i can imagine it now the girl does this but when she moves during the ride she falls off and falls into a street with a scary molesting hobo( hobo looks at her and think off dirty thoughts to do with her OxO) XD

Ive never seen a girl do that honestly

If they position right the vibrations of the engine will send them into ecstasy.

to hop off quickly if the driver hit a car, so we wouldn't be blame for the wreck

tiffany f has the best answer. i died laughing...tell it as a joke tiffany lol

so that the bugs wont bite there.

idk, i never seen a girl do that. if they did, they probably might fall off.
