I look at their dashboard as they go by ... a stuffed animal, an I-phone docking station, and swinging from their rearview mirror...such a useful device!... some dogshit whose purpose must be to numb their senses of movement in front of their vehicle. Calming! When I signal, these jokers suddenly accelerate to block my path. They get on the freeway doing 45 and immediately move over to the passing lane. When they want to change lanes, the first thing they do--before looking or signaling or anything--is tap their brakes and slow down about 5mph. I suspect the Google self-driving cars will be quite lame and still get acceptance.
