As a GA pilot, I cringe everytime I gas up and spill a little on myself or on the ground. That lead can't get out fast enough! But it is also incorrect to draw a parallel to cars, because there was enough volume for cars to transition gently to unleaded gas; you could get both for a while. There is not enough volume of 100LL for FBOs to have two tanks, so, the switchover will have to be all at once. That's why the "drop-in replacement fuel" search is going on... Don't know if it will come to fruition, but if it does, sure makes the problem a lot easier. Today, though, it's frustrating to have an airplane that I know could run fine on ethanol-free, lead-free 92 octane motor gas, but am required by law (unless I buy an STC) and by practicality (what airports sell) to use leaded fuel.
