To get everyone up to speed on what we can expect come 2019, here's what we can expect with Passive and Active Safety Tech. Keep in mind some features might get added from now till then, so this is not a complete list:
If the engine and gearbox brakes away from their mounts, would they not just get pushed into the cabin anyways? Or I just have no ides how those parts move under he hood in the event of a crash.
That depends on how the frame has been structured around the cabin which in this case could very well mean the engine once dismounted won't have the capacity or force to even cause the slightest of damage to the cabin.
