I don't antagonize anyone in a vehicle that weighs more than me. Part of your problem may have been the last cyclist the driver met a few miles before encountering you. In both the Corvette and Miata forums I follow cyclists are a hatred group....and I hate to admit it, but much of the behavior that causes it is exactly how the A level roadies ride when on the road. It hurts the rest of us because of their actions. Increasingly, I exercise my right to concealed carry while cycling. If I have to defend myself against somebody like you ran into (regardless of why they are upset), I will. All you can do now is follow up, help search out the vehicle and press charges.
