You mean like the carbon fiber Monocoque chassis?321apex wrote:The history shows that implementation of bold new technical inventions often proves to be unsafe and people get hurt.
In fairness, they weren't trying very hard, if at all for most of those decades.321apex wrote: The fuel cell safety took many years if not decades to figure out to make it safe.
The basic system has been around in some form or other since 2009. Tesla and other carmakers has been building cars with much higher quantities of stored energy for years prior to that.321apex wrote:significant voltage on board is really very new.
In Kubica's case, the roll hoop was fully exposed and completely visible.321apex wrote: Imagine a crash similar to Kubica in Montreal few years back, with car landing upside down. How can track workers help extricate the driver if ES system is damaged putting the whole car is under electricity? They can't see the indicator LEDs in roll hoop burried in mud.
The cell should be completely isolated from the chassis, and the cell should shut itself off in the event of a crash or if it detects a short. The battery pack catching on fire for no apparent reason is probably a bigger safety risk.
Not to say that there are not safety concerns with such high voltage systems, but the people involved are:
a) not clueless
b) not inexperienced.
At the moment, there isn't much reason to believe the ERS systems make the cars significantly more dangerous. This may change in the future, but for now everything I've seen suggests the safety concerns have been adequately addressed.
