I have a set on my gravel bike which is probably a better use case than road, but my favorite thing about it is the confidence it gives you after you have an issue. Rather than wondering if a puncture has fully sealed or second guessing if a tire starts feeling soft mid-ride I can just keep an eye on the pressure without stopping. On gravel especially I like knowing the tires are okay during chunky descents. The three wishes I have for them before adding to other bikes are cleaner integration, better price, and doubling as a wheel speed sensor.

This totally looks like something that really is useful only if you race. If you are a recreational rider without any ambitions to ride, you can just check pressure before a ride and everything is fine.
