ELI5: What prevents Tesla cars that are powered by lithium ion from exploding in a traffic wreck?

The battery is protected by an armor plate made from aluminum and/or titanium (depending on model) and divided into separate compartments. This provides decent protection against damage to the battery that could cause it to catch fire.

Battery fire is still a risk, but remember that you aren't comparing it to no risk at all, you're comparing it to a risk of fire from a spilled tank of gas, and compared to that it really isn't bad at all.
