Stupid thing to do. 35 mph = 51 ft/sec. Reaction time = 0.5 sec for the fastest people under near-perfect situations. 0.5 sec at 51 ft/sec = 25 feet. Typical drafting distance = 10 feet or so. In other words, when that bus or truck or car does a sudden, surprise, hard braking, it won't matter if you think your bike can stop faster than a bus, truck, or car. You will be eating the rear bumper before you've even grabbed your brake.
