Bugeyes.com are the mirrors I use.
They work awesome, and attach to your helmet.
I can see anyone coming up behind me with just a tiny change in angle of vision.
I bought mine for only $11 or $12.
When I'm MB'ing,
I wear an armored Jacket (Tourmaster Jett, $89)
some motocross gloves, and a full face helmet.
It's what I wear whenever I ride any 2 wheel motorized vehicle.
Better safe than sorry.
It only took me one sorry moment and some road rash/broken bones
to realize that this gear is mandatory for my safety.
Really sorry for your war wounds, but maybe this is a sign to
get up on the protective gear.
As far as sit down scooters go, I think they are more dangerous.
Sitting low in the middle of traffic on one of those things makes me sooo nervous.
I prefer to be on the side of the road, with only 1 or 2 cars to worry about,
rather than worrying about every retard with a cellphone driving all around me.
I ride goped stand up scooters though,
and you have to ride on the side like a bicycle, so they feel as safe as a MB to me.
Wishing you fast healing.
