Once while waiting at a red light I had a carload of smarta$$ teenagers yell at me, "Get a car you idiot!" They laughed out loud as they drove off on the green light. Needless to say, I quickly caught up to them once the traffic came to a gridlock and as I passed them (you guessed it) I yelled, "Get a bike you idiots!" and as I rode away, they never caught up to me.
And about bike costs, my hubby and I used to use his old El Camino to haul around our mountain bikes. The ongoing joke amongst our friends was that the bikes increased the value of the El Camino by 300%.
