> If you try even triple energy density of Li-Ion battery (0.875MJ/kg x 3) you're right next to gunpowder which has energy density of 3 MJ/kg. If you want increase it 5 times you're now in TNT territory (4.6 MJ/kg).

> Would you prefer car that can do half the range or the one that goes further but literally has 500Kg of TNT under your ass ?

I heard that there are some nut jobs out there that attempt to drive vehicles with 43.1MJ/Kg. Won't catch me near a diesel though. That must be, by the arguments above, 10x more dangerous than TNT.
