During lightning, i hear that being inside your car is safe, but what if it's an electric car?

There doesn't seem: to be any difference when lightening hits an electric car that is moving. There have been reports, however, that if the car is motionless and being charged, a specific (not all) lightning strike may communicate with the car's electrical systems/charging batteries and cause dysfunction/damage. I suppose not charging the vehicle during a storm is a possible strategy. Good wishes:)

Still safe: It is being inside a metal cage, rather than the car per se, that is protective. Electric, gas or diesel will not make a difference.

Car is safe if metal: As long as the car has a metal top and sides and you are not touching metal, the electrical current will travel around you and then makes contact with the ground which then completes the circuit. The type of engine makes no difference. For more lightning information, see http://science.howstuffworks.com/nature/natural-disasters/lightning8.htm

Still Good: The reason you're safe from lightening is that you're surrounded by metal. What physicists call a Faraday Cage. The lightening can't get inside. The type of motor makes no difference.

No difference: The type of car does not make any difference on the protection that it brings. Hope this helps.

Gas/Electric No Diff: Both types of cars are insulated from the ground by Rubber tires

Still insulated just: like in a regular car because of the tires (rubber). But, don't touch any metal, just in case. And, your car will be toast if hit by lightening, just like in a "regular" car, only the expense to repair it will be astronomical...

Grounding: Grounding still occurs with the rubber tires to the ground, like a gasoline powered internal combustion engine vehicle.

The "safety": comes from the fact that it is on rubber tires so won't conduct electricity. Type of motive force (engine/motor) is irrelevant.
