For those of you considering operating around electric vehicles, beware of the copious noise emitted by the BMW i3.
I was sitting in a parking lot, engine off, operating mobile on 10m during the recent band openings. Rather abruptly, the band's noise floor increased to mid-scale on the S-meter. I briefly wondered if propagation had suddenly changed, and then I noticed a BMW i3 pass behind me and leave the lot.
The noise left as well... I was back to a nice quiet band floor.
I didn't have time to switch over to 2m/70cm SSB and see how far up the racket extended.
I stumbled across an article relating much of the same, today.

So, save the planet or save the spectrum. Perhaps not both at the same time? :-)
