It's all good.
Just an FYI, remember you don't always have cell service. Travel out west
plenty of times I loose reception here and there in the middle of TX,NM,AZ,etc... Maybe you get a wrecker service, but say you have hours to wait? I'd rather pop on the spare. Anywho, It's good to have options. Run flats are good for 50 miles they say. Drive long distance and chances are you'll ruin them and then need them relplaced. Hopefully they are in stock
It all comes down to the one moment you're hundreds or miles in the middle of "bum f_ck no where" and your options are limited. It's good to have backup and then some more.
If you're DDing in the city, take the spare and accessories out. Chances are you'll never need them. Same on a trip I suppose. But insurance is nice.
Yeah, Americans want it all. Then again no one forces you to buy American cars. Buy what makes you happy. For me it's a WK2 SRT8. If a spare tire is gonna slow it down, then it gives me more reasons to mod and go faster
SRT products are still one hell of a machine. Even if it comes with a spare.
