Ever noticed that whether a car is red, blue, white or black, the tyres are almost always black? I always assumed it was simply the natural color of rubber, but there's actually some interesting chemistry and engineering behind it. explanation of why modern tyres are black

Who it's for: anyone who ends up driving somewhere with friends or family in more than one car. Road trips, car meets, a weekend away, moving house.

What it does: everyone can talk hands-free the whole way, see each other on one map, and follow the same route. If someone misses the exit, the others see it and can talk them back.

Where it's at: it works, I've driven with it a lot, and it's now on TestFlight. I've only tested in a handful of cars, so I don't know yet what breaks in yours.

What I'm asking: take it on one real drive with at least one other car and tell me what confused you or went wrong. Testing across different hardware, cars and mics is where im looking to you for help.

iPhone with iOS 18 or later, and every car in the group needs it. CarPlay is optional.
