About 25% Distractions like cell phones, GPS, maps, texting, eating, etc

brakes and tires are important, but... probably not the first priority for investments.
Easy ways to give yourself much higher odds:
take care of your heart, dodge the cancer bullets, dodge the stroke bullets, get a flu shot, use hand rails so you don't fall, watch what poisons you eat, turn off the cell phones when driving, don't drink alchohol when you might drive, do your maintenance regularly, stay awake, no speeding, etc. Somewhere way down the list, is TPMS.
