Not the insectothopter (necessarily) but the lightweight, cheap (vis-a-vis-the big multi-million dollar thing) personal helicopter. For the cost of a (well, OK, with all the bells-and-whistles) sedan, avoid the snarl. Get your earphones and sound proof your house. Oh, yikes. I hear helicopters are the thing in Sao Paulo where the traffic makes even Mexico City's look mild.
