Doesn't matter.
The initial suggestion was of a ban in 2030 from 10 countries that already had plans of banning fossil fuels from 2030 or sooner.
The 2035 deadline was a compromise to allow the car manufacturers to get up to speed. If they try to prolong that, some countries might just go back to their local legislation and ban the cars even sooner.
EU can potentially claim that such bans are against the free trade in EU and force it through, but they can never actually force anyone to buy the cars.
The decision of switching to EVs is entirely up to the local drivers, regardless of what arbitrary deadline the manufacturers try to lobby through EU.
Even in France and Germany, who produce fossil fuel cars, there are cities with environmental zones banning fossil fuel cars. Just as it today doesn't make any sense for people near Berlin to buy a diesel car that they can't drive in Berlin, every potential car buyer in all of EU are going to have to consider if they can even use or resell a fossil fuel car in their local area within the expected lifetime of a car.
