Approaching Cameron Toll from Craigmillar direction. I'm passed a little closely at a traffic island, but shrug that one off and move in behind the car. It's then I notice that the lady driving, with her teenage son in the passenger seat obviously being taken to school, has whipped out her phone and is checking something on it. Not a call, but swiping between screens. I can only put this down to her almost not noticing the lights ahead had turned red.
Bizarrely she actually managed to stop without going entirely into the ASL, so I filter in front and make a motion of holding a phone in my hand, giving a glower and shaking my head (I'm deadly at charades). She tailgates me as the lights go green, but I'm heading on the 'City Centre' road, while she's heading up Old Dalkeith Road, so contents herself with roaring past me, and doing that thing with your hand that you do to say someone is talking too much (little bit odd).
Given she had a passenger who could have checked her phone if there was something urgent, all she's basically done is taught her son that breaking the law is fine, doing something that could potentially end a life is fine, and if anyone points out that it's not fine you can attempt to bully them and get angry at them.
Well done, a fine example to be setting your child.
