Only problem is, if you see the bomb detonate, there's several hitches in this plan: First off, the era of large metal bombers flying over cities to unleash their nukes is over. These days, nukes are "dropped" on cities by ICB Ms , which means the warhead would come in at about the speed of an asteroid, making it almost impossible to actually see until it, well, explodes. Secondly, if you're far enough away that you see the detonation yet still in a condition to get into a car, you likely won't be vaporized, since the vaporization is caused by the heat of the initial flash. Crushed by debris thrown into the air by the shockwave or by the shockwave itself, maybe, but this still carries the remote possibility of surviving and ending up dying from injuries and radiation, which is not a fun time at all. The third hitch is that if you see a nuclear bomb detonate, it's likely the last thing you're going to see, considering that the flash is enough to permanently blind you. So congrats, now you're blinded, injured by flying debris, and suffering from radiation poisoning. Have a nice death. (The positive side of this is that, again, if you're within visual sight of a nuclear detonation and aren't immediately vaporized or shredded by the shockwave in the next few seconds, you pose a real chance of either not being in the fallout zone, or being able to move out of it before the radiation takes a noticeable effect. Not a guarantee, mind you, but still a better chance than the poor lot who now exist as little more than shadows scorched onto the wall.)
