If you have learnt to drive, that's the point ! Good all round observations, reinforces the decision on if to indicate, or not !
To autonomically indicate , often means you haven't observed proper, so clicking switches means you can do what you intend to.
That's wrong , you do not need to indicate to pass a line of parked cars, the reasons being there may be a turn on the right ,which you do not intend to take,which to oncoming traffic can be confusing. To overtake or pass your road positioning should be all that's required, as long as oncoming traffic is being observant of course.
I was riding my motorbike on a m- way the other day, made my observations before changing lane, when one of these stupid autonomic Tesla things chose exactly that moment to overtake me, I cancelled my manoeuvre to maintain my safety , but plainly this Tesla thing was set up to 'drive' at preset speed and distance, ....this to my mind isn't safe, it's fine if everyone else has these systems, but it doesn't abdicate the driver from taking absolute control.
Observations make safe driving ,not auto drive by wire systems.
