…if you can be bothered to do a LOT of planning with routes:

Tomtom warns of ‘dangerous roads’ as speed warning devices are illegal here…I use the app on a smartphone and get audible alerts via my headset. Probably warns of around 75% of the cameras!
There will usually also be a warning sign, though when they state cameras for 20 kilometres, not a big help!
Just like anywhere, you need to stay alert.
Atm UK plates will only get fines and not points. Likewise, I can pick up ‘fines’
from Austria, Germany and elsewhere and only get fines. Though if stopped by Police anywhere in Europe travelling at ‘extreme’ speed you will risk losing your vehicle.
Last year in Austria a guy on our trip got caught at 70kph over, €1600 fine…no points as he had UK plates.
Again, have fun, just keep it a little bit real and you will be fine.
A group of us got stopped exiting a village in the French Alps a few years back breaking the limit, the gendarmes saw the UK plates and said to pay more attention and keep the speed down. Waved us away with a smile.
