BMW X5 driver repeatedly fails to understand big rig braking distances

Nobody should be shocked that a big, heavy vehicle like a semi truck takes a longer distance to stop than the average passenger car; it's just basic physics. However, this BMW X5 driver seemingly has a major problem grasping the concept, and it results in some serious damage to the back of his SUV.
The whole incident is very confusing to watch. The BMW doesn't even seem to have a reason to slow down before the semi slams into the back of it at fairly high speed. But to make the situation even weirder, the crashes just keep happening again and again.
To give the BMW driver a little credit, he appears amazingly calm when surveying the damage afterward. But you have to wonder what this guy was thinking when trying a harebrained move like this. Check out the video to watch the carnage unfold.

BMW 1 Series prototype packs direct water injection

Just a few months ago, BMW showcased an M4 that was modified to serve as the safety car for the MotoGP racing series. The flashing lights and emergency equipment, however, weren't the only modifications BMW made to the performance coupe. It also packed an innovative new water injection system. And now it's furthering the development of that system by running it in a 1 Series hatchback as well. Revealed at the BMW Group Innovation Days 2015 event, this five-door 1 Series packs a three-cylinder gasoline engine – like the one found in a Mini or i8 – but fitted with the direct water injection system. In this application, the system sprays a fine mist of water – yep, regular old H2O – right into the combustion chamber. While mixing water with gasoline normally wouldn't be recommended, in this case it evaporates immediately and helps cool the engine from the inside, allowing it to run at higher efficiency. That cooler running engine brings with it several benefits. It delivers improved fuel economy and lower emissions, to start. It also allows for an earlier ignition point, higher compression ratio, and higher boost pressure in turbocharged engines, delivering increased output. It even cuts down on engine knocking (where combustion occurs spontaneously), reduces wear and tear on the engine, and makes better use of lower octane levels. If that sounds like a win-win-win... win (we're losing count of all the wins here), it's because BMW just may be on to something. Of course it does require a water tank to be fitted on board, which means added weight, but instead of requiring the driver fill up the water tank, BMW has fitted this prototype with a system that replenishes the water level from the air conditioning system when the vehicle is switched off. So unless it's being driven in a particularly extreme climate, it doesn't even need topping up. Add one more "win" to the list, then. Extra power, improved real-world fuel economy: Direct water injection enhances efficiency. With direct water injection for turbocharged petrol engines, the BMW Group has again succeeded in enhancing the capabilities of conventional engine technology through an ongoing process of refinement and improvement. The precisely controlled injection of water into the engine cylinders produces a cooling effect that boosts power and torque, particularly when operating at or near full throttle, while at the same time reducing fuel consumption and emissions.

Forza Motorsport profiles courageous paralyzed racer

It's easy to look at racing video games as just a time waster or a hobby. In reality, though, they're often powerful tools for aspiring racers to learn tracks, race craft and how to set up a car in an easily accessible, risk-free environment. We aren't just talking about proper computer-based sims, like iRacing. Console-based racers like Forza Motorsport and Gran Turismo provide a test bed for racers of all sorts.
For Mario Bonfante, Jr., a former motorcycle racer that was involved in a brutal accident that left him in a wheelchair with only limited use of his arms, Forza is a bit more. It allows him to perfect the setup of his personal racecar, a heavily modified E46 BMW M3, complete with hand controls.
