That's not true. Maybe it's true of whatever you personally drive down there, but here in the US many cars have the cigarette lighters powered when the car doesn't even have keys in. For example, the two Fords we have have them powered, but I don't think the VW I used to have did.
The figure is probably closer to 50% than 95%, and I'm not very sure about the 50%. But 1 in 20? No way.

Cigarette lighters are almost always fused. They generally don't do very well with currents over 10 amps, so if you have a serious charger and are charging big batteries, you may need to run some of your own wires. I also suggest having a fuse in your cigarette lighter adapter, preferably one smaller than the one in the car for that circuit so it blows first.

Overnight is 2 hours? The problem is that many fast chargers are 12 volts, and many people don't have 110 v -> 12 volt transformers set up for that, so they just do it in their car instead.

Personally, I do a lot of my charging in the car, often on the way to the field. It's just convenient. But I have one Triton for the car, one Triton for the house, and a few others for various things.
