Which is great, but not putting your fuel tank under your ass would be a good step towards minimisation of consequences like, say, fires, don't you think?
Of course this is the problem. Tesla have to worry about fitting in a battery which weight compared to the fabric of the car a lot and takes up space so it needs to be distributed around evenly. It does catch fire when the contents are exposed air though.
With good old fashioned petrol (gas for you americans) you just have this incredibly explosive stuff that you can cram into a small corner of the car and puts lots of protection around. Of course you have to protect it better because the stuff does not catch fire, it explodes but only if exposed to a source of ignition unlike a battery.
The real problem though is that the raw material needed top make exploding liquid fuel is running out, it simply will not last for ever. This can be mitigated though by moving to diesel engines which can be run off a wider variety of fuels, some of which come from other stuff instead of oil but that comes at a loss of performance.
So in comes Tesla, he realises that while there may be a way of running crap like family saloons on recycled chip fat the sports car of the future will need to work differently when petrol runs out. His early products might not be as good as some of the traditional cars that have been evolving for 100 years, but who cares because petrol based cars simply have no long term future.
It might take 20 years to run out of oil that can be refined into petrol, it might take 50. Hell, one more decent war in the middle east the price of oil might go so damn skywards that nobody can afford any within 5 years as we use the rest of the planets up double quick. The point though is that even if it takes as long as 50 years the price of gas at the pump is just going to go up and up.
Once you look at it this way you realise that even if Tesla make a loss for the next 10 years, they will amass enough patents that they will ultimately be laughing all the way to the bank.
