BMW Concept Bike

eric3579 says...

Look Mutter, nein helmut!

“The vision vehicle will act with foresight and is able to protect the rider at any time,” says Heinrich. Driver assistance features will continually monitor the environment, the route, the speed, the angle of lean, and myriad other factors, intervening to ensure the rider can’t crash. Gyroscopes keep the bike upright when stationary, so you can’t even fall when stopped. BMW’s roughly an eternity from actually telling riders to ditch traditional safety gear, but things like traction control, hill start assist, and antilock brakes are already making it harder to kill yourself on two wheels.

I like how its technology gets rid of the need for a helmut.

Debunking Gun Control Arguments

Drachen_Jager says...

That's BS.

With a 5 round maximum capacity you're going to be reloading a lot and there's no reasonable argument why anyone needs more for hunting (and home defence is a red herring).

I think the whole law/culture issue addressed above is actually linked. Take the example of the Autobahn which is very much a parallel. Germans made a law saying you can drive as fast as you want on certain stretches of highway, a culture of high-speed driving developed, people die. The majority in Germany wants to do away with them, but the 10% who want to drive recklessly in their BMWs and Mercedes along with the manufacturers fight new legislation every time.

The law created the culture, and now the culture is preventing the laws from being changed. Just as in the US, the cycle has to break somewhere. Government can't legislate the culture, but they can change the laws and if the US ever gets to a point where guns aren't in the hands of whoever wants one then the argument for needing a 'home security' weapon drops. People feel safer, there are fewer shootings and the whole situation de-escalates.

I'm not saying barring suspected terrorists from owning firearms will accomplish that, but it would be a (very) modest start in the right direction.

Then you end up with people taping mags together and reloading within a second or so.
Even faster if they count shots and stop firing at capacity-1 before reloading.
There are work-arounds...

Russian Drifting

newtboy says...

From my experience, and physics class, that should only be true if your brakes suck. Physics don't lie, and I was taught that static friction is ALWAYS greater than kinetic friction...meaning rolling tires grip better than sliding tires every time. If your brakes are able to grip with more 'stopping' force than the sliding tire produces and still allow 'slip', they should be able to stop you faster than sliding.

Perhaps on ice that's true, or other slippery surfaces where the sensors get confused, or with really bad or broken ABS, but good ABS seriously reduces the distance to stop AND retains control by rapidly (thousands per second) pulsing the braking force up to maximum possible force without stopping the rotation. That should be more stopping force than locked tires can produce if the brakes are in good condition.

I've been in the car when an idiot friend decided to prove it to me, and slammed on his new BMW's brakes at about 70mph. The seatbelt hit so hard I had the wind knocked out of me, and we stopped ridiculously fast (WAY faster than when I've locked up non-abs cars on the freeway...repeatedly). Afterwards, he needed new brakes all around, because they gripped so hard and hot it warped the new rotors, but never locked up the tires...retaining static friction between the road and tire. Dumb...but informative.

Newt, I gotta tell ya, there is no quicker way to stop than locking up all four wheels, other than spinning in the other direction on a dry surface to kill inertia (makes it worse on ice). You just have no control. ABS brake systems actually increase the distance needed to stop, they just provide the ability to control and turn at the same time.
