I guess if I could remember to put it back when I was leaving town, that would be a reasonable approach.
My Fiat 500 came with the spare as an option, otherwise the standard was a compressor that had fix-a-flat in it and also worked as just a compressor. I wish I'd kept that when I sold the car, as that was pure gold, and always enough to get me to a tire shop for a real fix. I have been fortunate in my many years of driving to have never had a flat that couldn't be babied to a tire shop either with slow/careful driving or a quick overfill at the gas station. Just had one fixed 2 weeks ago before a trip across the mountains...once again, able to baby it in to the tire shop to get the nail removed and tire patched.
