Gasoline is not explosive, it requires oxygen to burn. We wouldn't allow normal passenger vehicles to drive around with big tanks of explosives.

  Why hasn't anyone invest into synthetic petrol that is carbon neutral?

    ... like the DOE, ARPA, USDA, and NSF? They all are, I've personally worked on projects funded by these organizations to make carbon neutral petrol replacements. Heck, even the oil majors are funding that kind of work, they see the writing on the wall even if politicians play-act that the fossil fuel party will continue indefinitely.

  Yes, it requires oxygen, which happens to be all around and inside a vehicle typically. I'm not sure what your point is. If a fuel tank is ruptured it can lead to fire and/or explosion. If a battery is ruptured the risk of fire is a lot less. Maybe batteries carry a greater risk of spontaneously combusting, but I don't think that makes them more dangerous than carrying a tank of flammable liquid around

    Petrol is very safe for the energy density it has due to the relatively slow rate at which outside oxygen gets fed into the flame causing a burn rather than explosion. TNT is far less energy dense (1/5 iirc) but because it contains oxygen it is far more dangerous and explosive. A very high energy density battery is likely to be closer to TNT in its reaction and not have the requirement of needing outside oxigen to keep the reaction speed in check (but really this depends on the exact technology of the battery)
