In the UK it is legal to ride between lanes of stationary or almost stationary vehicles. Once the speeds get higher than walking speed it becomes more of a grey area. Riding between lanes of moving traffic at motorway speeds would definitely be illegal and highly dangerous.

I cannot get on the bike without helmet and gloves nor can I drive a car without a seat belt...but life is all about chances and luck or the lack of it...the whole universe is "total chaos in complete balance"
you can be rackless but have luck on your side and live till ripe old age ...or you can be extra cautious but unlucky and die young in a freak accident ... and of course anything in between.
...life is like a box of chocolates

a helmet and so on.

Yeah , but your not the only victim if it all turns to shit. My partner came out of my "accident" worse off than me and she wasn't even there , seeing me and all my injuries , being told I wasn't expected to live at the hospital , then months in hospital , and I wont ever forget the look on my Mums face when she got to the intensive care unit , or when they hauled me off for emergency surgery when I started bleeding internally ( again ! ) . If you can be 100% selfish , then your OK , but others go thru the mincer when you crash your brains out too

dude, just what`s wrong with you ?
It`s two guys on a scooter...

Looks like a girl on the back to me. Very pretty too, with her helmet on back to front!

if wearing a helmet makes you look uncool you can try one of these

Watch your tongue, boy! Remember, the Germans now own Ducati ...
