Bethesda Supercharger - don't bother
I tried the Bethesda Supercharger once (early am so no wait) and it only produced 60mi per hour so I left after 10 min. eVgo Chademo is better - 130mi per hour. I use that when I have to make multiple daily trips in the DC Metro area, like Olney to Herndon to Baltimore... So, I'm all for them moving it; upgrade to newer units and get it out of the mall garage, and increase the number of chargers..
I think there is a nag. Just spend 30 minutes testing this.
Interstate road, 12-lanes divided (6 each direction), every 3 minutes for 12 minutes (i.e. 4 times) then I got off. Exactly at the 3minute mark.
Local road, 6 lanes (3 each direction, grass divider, though the car thought it was an undivided highway and restricted AP), every 1minute for 4 minutes (i.e. 4 times).
Then I held the wheel for about 5minutes, and still on the local road it let me drive for 2 minutes, then nagged, and then back down to 1 minute. I think it might be giving me leeway if it sees me holding the wheel.
Up until this evening I was in the "nah, there's no nag" category, but I think there is, as it's repetitive (in whole minute intervals), and I also think the nag is different on different types of roads.

I'll grab some photos later if no one did yet. It's pretty good (haven't seen bikes yet, it's cold out now) with cars and trucks. It can now show up to 2 (or at least's that's what I've seen) cars per lane, so I've had 5 cars on my screen at the same time.
The issue is that only detects the cars in neighboring lanes that are about 1 cars length ahead of you (I guess the camera isn't wide enough), so it never shows cars parallel to your car.

I have no problem stopping if I need it, but it's so close to home (Fairfax) that I don't see a point of ever going.
FTR, I've never actually been to Bethesda supercharger. Might need to visit it before they move it.

I've seen trucks, no motorcycles yet (it's cold). Trucks are hit or miss, I've had trucks convert into cars, lol.
