I think that will be an issue they haven't considered. Many will sit with their foot most of the way down because it will be hard to judge the pedal position when it's not responding to input. Then suddenly unexpected acceleration when passing a NSL sign.
If they do that's a fault of the driver not the tech, and a great argument for having the car do all the driving...
It's not exactly rocket science or hard to judge your foot position on the pedal.
Is the EU expecting every car company to be able to implement this technology? What about a small start up that maybe couldn't afford the development and implementation of this technology? It makes the price of entry into the market even higher and gives current manufacturers more of a hold on the market
Absolutely no different to at the moment
The cost of this compared to the other regulatory requirements for putting a car on the market is going to be small, there will be companies that make the technology and just require the car manufacturer to design with it in mind.
This is basically the same as things like Air bags, ABS etc. there will be companies that develop their own versions of the systems, and there will be companies that just buy an off the shelf design and make minor modifications for their vehicle.
It will likley be a plug and play module in most cases because you can bet that the likes of Vauxhall or VW group will not be making a different system for every model of car they sell, they'll be making a general unit that can be easily customised per model and be willing to sell it to third parties (as they things like engines etc), or they'll buy it in from a specialist manufacturer who does the customisation beforehand like they do for radios and other electronics.
I suspect for some manufacturers who are already putting most of the tech into their higher end models, it's likely already reaching the point where it's cheaper to include it in every car sold rather than say only on certain options (as happened with ABS, ESC, airbags, power steering, electric windows, air conditioning etc), as once the technology reaches a certain point it's easier to include it as standard than do multiple variants on the production line.
There will also likely be exemptions for certain types of car manufacturing (IE kit cars or volumes under X per year), as there is at the moment for certain types of testing and approval, with the vehicles instead being tested under a different set of standards, or the additional cost with not be noticable compared to the cost of any car that is effectively custom made in small volumes (where you're usually already paying a lot more because you don't get the cost benefit of volume production).
