I am in continental europe at present. When entering a town or village its often only the place name that indicates the national urban limit now applies. There are no roundels. In one case my satnav said 50kph (The usual urban limit), but every few hundred metres a very large speed bump had recently been installed ,each with its own speed bump warning and 30KPH roundel. The bumps were large and you wouldnt want to hit one at more than 30kph, but I was left in doubt, was it 50 kph through the entire village or 30 kph -( It was a very wide main road ) . To add further confusion there were still older 40 kph roundels displayed with a conditional plate that this 'lower' (than 50 kph) limit applied if it was wet or icy. I also saw these 40kph signs in places where there was no doubt the limit in good weather is 90 kph. The recognition system recognised just the 40 kph roundel so presumably the new cars would at times be beeping when I am not in fact exceeding the limit.
I can probably tolerate just 3 beeps.
Steve-M's earlier comment that the new satnav system gives better support to the speed monitoring system suggests to me it may make more use of gps location (even if you dont have a satnav display option) to establish the applicable speed limit, rather than relying entirely on possibly absent or confusing roundel signs.
There has to be a way, what about putting duct tape over the camera so it don't know what the speed limit is?
PS. I don't recommend doing that because it might bork lane assist and adaptive cruise.
I saw, but didnt read, a recent news feed that says there will be fines if you dont have the system after 1 july. I didnt read it as i took it as typical journalist 'click bait' ,as you dont need to retro fit it to older cars, and new cars will have it ,like it or not. But its quite likely that knobbllng a car that must have it, by for instance masking, or disabling the bleeper would be illegal. It might not be illegal to modify a car first registered before the cut off date ,but it might void your insurance.
But what about drivers with hearing loss . Are they lucky to avoid the annoying bleeps, or at greater risk from the consequences of unbridled speeding? Might insurers increase their premiums?
