There is something nerve racking about getting to your car when things go wrong during a mission, "Will I make it"? The car in this case is a sanctuary that hopefully will buy you life until things balance out. Equally, when you leave your base for a destination, there's too much comfort in believing your beefed vehicle will buy you a get out of jail free token, as long as you drive well, don't take too much damage and don't get pulled out - when driving through large numbers of the undead.
But what if, unbeknownst to you, during anytime behind the wheel, your tire blows out? Once it would happen an immediate sense of dread would present itself. The car would either be un-drivable or greatly have its steering / speed reduced, provided you didn't fix it. The noise alone from the tire burst would surely attract undesirables. Can you fix it in time before they get to you? Perhaps you're a mechanic or have the quirk skill "driving", maybe this allows the time taken from getting out of the vehicle, kneeling at the tire, and repairing it - to shorten??
Regardless, having the game randomly (maybe in settings it can be disabled or change %) blow out a tire while on the road could be absolutely devastating and require quick wit, immediate action and a grand percentage of fortune.
