Should we allow neighbours to add new driveway going on to our drive?

So we have a bit of an odd situation.

Our property is one of four fed by a private driveway. There's a set of garages on the drive with one garage per house. Then our own private driveway breaks off which is where we park.

We own the driveway outright and the neighbours have rights of access to get their car into the garage and then foot access to the rear of each of their properties. Meaning each neighbour can park only one car in their garage.

Due to the way the land was divided up over the years only one neighbour is obliged to pay "a fair proportion of upkeep" towards the shared part of the drive. Which means we pay 3/4 and they pay 1/4.

That same neighbour wants to tear down the boundary between their back garden and our driveway so that they can put their own private driveway in for 2-3 cars which would go onto the "shared" part of our driveway.

They've asked for permission and I offered agreement in return for splitting maintenance on the shared part 50/50 going forward. My reasoning being the other two neighbours can't physically expand beyond their current one car access. Whereas I and the neighbour wanting the drive would have access with 3-4 cars each.

I think this is reasonable but they're quite upset by the idea.

What would you do? And am I being unreasonable or overly generous with my offer?
