Suggestion:
Adding a new item that allows people to replace popped tires with TEMPORARY spare tires, that pop after a specific distance or speed is reached. No mechanical expertise necessary. Would be titled “Spare Tire”
How will it expand RP: In real life, you can put on a spare tire in a time of need, without needing to be a mechanic. Why should we need to drive on our rims to the nearest mechanic shop for a new tire or 2 in the city? Adding the “Spare Tire” item would give you a little bit of extra time for a mechanic shop to open as well, while you at least have something to drive on temporarily.
Im starting my own Roadside Assistance company, and being able to save you a bit of frustration with a spare tire would add to the experience.
