I'm guessing though that you're in the EU (I'm in the US where it is almost considered criminal to go speed limit on the highway)
The way to get to the city proper goes through country roads that probably used to only get a few dozen vehicles per hour, now having to handle massive traffic due to the new developments in this area (they're still building!)
They're working on reworking the roads but the speed limits are nonsensical because of this history.
I do wish it was even quieter tho. It's kinda of a shame you got a quiet EV but then add annoying bingbongs.
It was hard to find reputable numbers for all of Q1, so my source is only for january and february: https://www.reuters.com/business/autos-transportation/volksw...
Colour me skeptical. ODBII is just a protocol; it knows nothing of the modules on your buses. I think you will find you need the dealer software. Tools exist that implement big chunks of that functionality, but since they are built on reverse-engineering, the price approaches the dealer software anyway.
The only place i found the Mercedes software was a paid forum that obscures the links. Getting the cracks working was a magic incantation. It's similar for VAG. They won't sell you the software if you're not a dealer.
You will not get there with a £40 ebay special. If you can, please share what works, it will be of much interest to many.
Not sure if this has ever been implemented but I know from my time in automotive that there was the idea to exchange driving data with the insurer. If this becomes reality ignoring speed limits could increase your insurance premiums.
A lot of these features seem to assume that you're driving on a multi-lane motorway with well-marked lanes. I'm constantly being nudged by my ID.3 one way or another on rural roads. You can turn it off, but it turns itself back on the next time you unlock the car.
