Petrol cars are 100 times more likely to explode in a car crash...

Petrol cars are 100 times more likely to explode in a car crash due to the fuel tank over lithium batteries
which can explode in a car crash. Hydrogen cars are 7 times higher risk of exploding in a car crash.

Solid state batteries can't catch fire which are mainly lithium based but there are a few car companies not using lithium in their latest batteries
which also do not catch fire.

Most of us have mobile phones which are lithium based and some newer ones graphene based.
Lithium over charging can cause fires where graphene can't ever catch fire.

Cheap electric scooters from China are likely to catch fire due to over charging which is why you see so many
house fires where the scooter is the cause. They are often imported and bi passed the standards we have in Australia.

Think as soon as we see solid state batteries in cars then they'll take off as they never need replacing, fast charge and have far longer
ranges before they need re charging.

Current lithium based cars its not wise to fast charge if you want your battery to last longer where solid state batteries its fine to fast charge.
