If you're able to escape that masked killer, remember that cars typically aren't reliable. Battery life always yields to the strange and inconvenient horror time continuum, a force that's always sure to leave you stranded in your moment of need. Or in your moment of zombie horde attack. Before leaving the driveway, make sure you bring an extra set of keys (the first are sure to be lost during the initial attack) and consider a preemptive visit to a mechanic...who is probably an axe murderer anyway.
