Rant: Shitty fucking dangerous drivers

[John V]

On the other hand, this case in particular had a car going against a bike.
A car weighs about 1000kg... a bike, a mere 200kg.
If the speeds were comparable, we still have a net momentum in the direction of the car.... of about 4/5 of the car's speed.

It's also the composition and design of the vehicles. The car has crumple zones, seat belts, air bags - it's all designed so that the vehicle absorbs more energy and the occupants less.

Motorcycle - not so much.

I used to have a dirt bike and it was a lot of fun, but I'd never ride one on the roads. Motorcycles lose to just about everything but a squirrel.

It isn't faulty no, I can guarantee that.

Yes, it's faulty.

But in any case, whatever the speed was, somebody died from it, and I'm pretty sure they're not thinking about what speed they were travelling at when they died. I think the overriding lesson to be learnt here is that we will all die someday and all our bickering about velocity and energy will be totally meaningless and irrelevant (except for the 15yr old physics geek accessing this forum on the planet Mars 250 years from now).

IMO a lesson that should be learned is that motorcycles are inherently dangerous on roads.

I meant that the bruising is from the seat belts... sorry if it came out wrong!
