In my own experience, for the most part people seem to sit in their cars, more often than not using the 30-mins quick charge to have a nap or catch up on calls/emails. I've never seen people milling around charge points
Yep, and the charging stations ones I've seen on motorway services are all very brightly lit and under CCTV surveillance. Not trying to dismiss or minimise entirely legitimate concerns, just trying to provide a bit of reassurance.
