This is the shittiest handkerchief math ever. Your only considering fatalities- which comprise a small subset of the total number of accidents.
Secondly, you didn't actually provide a comparison. You simply remarked "Oh the chances of dying in a car accident is comparable to the chances of dying due to lightening therefor cars are safe" (whilst ignoring the 2 ORDERS OF MAGNITUDE difference between them, people struck by lightening != people killed by lightening and the fact that cars are not safe, as anyone who has ever driven will tell you).
