To think DS (16) saying he cycled 36mph speed on bike ride today is NOT ok?

What do other cycling parents think? Am I in the wrong? Just had massive row with DH ( and DS) who thinks it's OK for a solo teenager doing a ride out on his road bike in a rural area to reach speed of 36 mph (wearing shorts). I love him going out on his bike, great healthy exercise etc. Good for his mental health too. I cycle myself. But I told him going so fast is dangerous, not enough time to react if pothole, gravel on road etc. Obviously being a know all teen he was having none of it. I expected DH to agree and be worried re DS safety too but he went against me, said it was fine as long as he's getting out on his bike. Just don't tell his mother next time he goes so fast! I'm furious for lots of reasons.

Thanks - that's interesting, and there are lots of potholes round here !
The one I'm thinking of gives you 30 secs to respond and turn the alarm off then, if you don't/can't respond, it calls your primary emergency contact and texts your other contacts to let you know you need help and aren't responding.

We got one for our elderly dad and tried testing it by one of us wearing it and literally throwing ourselves to the floor - we couldn't set it off!
