A new type of airbag for motorcycles. If a mattress would jump under every rider before they go down, we wouldn't have injuries or messed up bikes anymore. lol
But really, I agree with VegasRider. I avoid vehicles with loads in the back regardless of if I'm on my bike or in my cage. Back in th day, I had a pickup with lumber on a rack stop next to me on a freeway off-ramp and every piece of lumber came off the front when he stopped. If he was behind me, it would have came through my back window and decapitated me (2-seater car). I was already stopped so I didn't have a choice if he was next to me or not. SInce then, I try to avoid vehicles with loads.
