The older I get, the faster I used to be ...
Not useful to assume, it's hard to know what was going on there.
Route checking etc who knows?
I still feel a few mins here or there is not a problem
Whether using a device to check a route, send a text or make a call is irrelevant, It is dangerous to do any of these things whilst on the move because one's attention is distracted from the road. It is instructive that Gaz links to Don't Phone and Drive at the bottom of his posts - brief quote - The main problems are distraction, be it from a conversation or by looking away from the road. It’s clear that looking down at your phone to read a text or push some buttons takes your eyes off the road and that is dangerous. But what is often overlooked as how having a conversation with someone on the phone affects you.
Exactly the same applies to using such a device on a bike - perhaps more so given the inherent instability of two wheels only. It wasn't illegal to use a hand held mobile phone in a car until relatively recently - perhaps it should be illegal to use one on a bike too.
