Alexddas, That's a nice list except...
Actually, a lot of people (including me) wear a jacket all the time when riding. Whenever I ride a bike, even in 45 Deg of sweltering Delhi heat, the riding jacket is always ON. Jackets are not only for cold/ wind but they also protect you in case of a fall. My riding jacket has shoulder and elbow armour and it has a mesh front. Its actually pretty airy in summers and inspires a lot of confidence when riding a bike.
Well, if you are unable to see his third wheel, then I guess you are too close to him!
Again, three wheeled bikes for the differently abled people is not uncommon....they are called '
Trikes'. Have a look here
