Hypothetical law change? Lorry on bike: lorry's fault. Bike on ped: bike's fault

It is banned??

Talking on the phone isn't banned just holding it (yes a simplification I know) the conversation is the distractor is it not.

there is no such think as total distraction, it's about the effect on your reaction times and your concentration levels. every person is different.

Very true

Some people who have slept badly could find making a decision on a busy road junction with a number of conflicting signs a serious challenge. enough to take all their concentration and for the entire approach to that junction fail to look in their mirrors, and fail to signal. this is fatal!

This CAN be fatal?

There is no fine for absent minded drivers as it can't be measured. but taking away obvious distractions that require usage of any of the senses is pretty straight forward thinking

If there is an incident there are laws.
