The best way to protect oneself from a possible thunder-strike is to remain in the car with the doors and windows closed. The car touches the earth through the rubber tyres which are insulators. So, the thunder is not attracted by the car as it does not liberate any charge in the air due to insulated connection to the earth. For all other cases, there are chances of thunder-strike.
