I appreciate the warning, I'm sure, but the Apocalypse is not an excuse for bad driving. In case of rapture, you are to pull over to the curb, set the parking brake and turn off the engine. Then you can go nuts.
If you cannot in good faith agree to take these steps, please turn your driver's license into the department of licensing and leave off driving altogether. Explain to your employer, if necessary, that you will not drive on religious grounds.
Safety First. Jesus Second.
That is all.
