In the city, not much of one. Rural roads with bad cell coverage at night in the dead of winter? Life or death situation.
That being said, I think a spare is unnecessary for 99% of drivers. In ~20 years of driving, I’ve only used a spare maybe 3 times, and those were more for convenience than necessity. My last car just had a pump, and I got a screw it in. I just aired it up and drove to the tire shop. After that I bought a plug kit for a quick roadside repair.
How is a flat tire an emergency?
