LOL love the sarcasm, but seriously going tubeless has saved me a lot of time. Last fall I retired this rear tire after ~2000 miles and it looked like this:
with 20 weeping spots, and each one involved a small wire or goat head that would have required stopping and putting a new tube in. But the tubeless sealant allowed me to keep rolling for 2000 miles.
I’ve had a tube tire pick up a goat head and start hissing loudly while descending at 35mph. Scary but I was able to keep calm and come to a controlled stop. And I’ve had a few tubeless tire incidents like that. From my POV an insert is about making a sudden loss of air at speed less dangerous, without having to go tubular.
