Back in '75 I was working outside of Las Vegas and had a Mustang pull up beside me at a light on Rancho and rev his engine while looking at me and my '66 Mercury Cyclone GTA. I didn't pay any attention to him, and we pulled up side-by-side again at the next light, the last light heading out of town. Same thing this time, he was driving right alongside me, so I decided to stomp on the gas pedal at 45 mph while downshifting my floor shift automatic into 2nd. I was up to about 65 mph in a couple of seconds when I shifted back into 3rd and he was nowhere to be seen. Was doing a modest 85 mph when I decided he wasn't going to try and catch up, so I slowed back down a bit.
