Plenty of EVs have air intakes. "Proportional' simply means the increase in drag caused by the cooling system compared with the overall drag of the car.

Well, one good thing about engineering is that it is not about beliefs!
The published data on the two EVs I have mentioned showed what I have described. That's based on wind tunnel testing. I'd love to see some other measured data, but that's all I have been able to find.
The diagram I have of the Taycan's cooling system shows two radiators, one each side at the front. They are about the size of those found in internal combustion engine Porsches.
