Chances are your tires actually DO have radio emitters in them - tire pressure sensors are wireless and send their measurements out on the 433 MHz band.

I’ve made this plenty of times. Whole canned tomatoes are usually better than diced - just break them up a bit by squishing them with a spoon when you put them in the pan. Needs to cook for a good while - 45 minutes out so. And add salt at the end to taste! But a super reliable sauce and requires very little equipment out prep.
