This disparity in size is a real challenge when driving.
For one, the issue of whether you can be SEEN is real. The size of a Miata, say, when alonside an Escalade. These folks in the large trucks and SUVs cannot see large areas around their vehicles.
Couple that with kids and cell phones and I think many of us are simply not there, visually. LIkely can't be heard either.
Now, if you ride a motorycle, you simply like risk.
I like risk, I guess.
