"Ah- sir, your bike is under the bus"
And I'd also like some suggestions for the rest of us who use those bus bike racks...how can we make sure this doesn't happen to us? The bus bike rack shown in your picture isn't like those that I've used, which are totally made of steel and have no springs as far as I know.
The pictured rack (above) looks a lot flimsier. I'd assume that front wheel stabilization bar and spring might fail in other instances. Could we keep the bike on the bus by using a bungie cord somehow? Perhaps to positively attach the clamp arm to the front wheel? What do you suggest? I don't like the option to ride my bike down the bus route, instead of using the bus.
