Now enter a car that catches fire as soon as it's in deep water. Now you have a WAY more serious problem, and cannot see or even breathe. This is a really bad problem to have and is something that could result in some deaths. They need more safegaurds to prevent mere immersion from destroying the car if nothing else so occupants can get out.
Wow, talk about FUD! First of all the occupants could of got out, because if you red the article, you'd know it happened AFTER the car was submerged. Secondly, SALT water is much worse for engines and batteries than fresh water.
I welcome any safety improvements that result from this, but when I buy a car, I don't expect it to perform like a submarine.
