To be fair, ICEs tend to cath fire while they are moving. That's the time every system in the car is most stressed.

That means the odds of it catching fire on your garage while you sleep are lower.

EVs by their turn are highly stressed while charging.

The way I see it, ICE vehicles have a different potential fire mechanism that isn't present in EVs.

Since ICE vehicles operate at much hotter temperatures, they inherently have a combustion potential due to leakages (brake fluid, gas, oil, etc). It's pretty common to have a bit of smoking from a fluid change, purely from accidental drips (even a little bit). If it's a continuous drip and hot enough areas such as exhaust, you can get a fire.

EVs just don't have anything that hot during normal operation. The operating temperature of both the electric motors and the batteries is much much lower than the temperature of engine operating temps (usually 200+F) or exhaust gas temperatures (something ridiculous like 1200F on catalytic converters, and 500F on exhaust piping).

This is not backed by any evidence while the opposite is shown in the referenced paper. Most ICE fires happen when parked according to actual data.
