alt Hacker NewsBrake fluid isn’t oil (generally speaking). EVs have electrical motor-driven power steering, not hydraulic. You scored correctly on the reduction box, which will need changing well after most people sell the car (>100K miles).

It’s hydraulic fluid, which is oil. It’s not formulated the same as engine oil, but it’s not far off gear oil.

I find it hard to believe that someone somewhere isn't making an EV with a electric pump to supply a traditional hydraulic steering system. If I had to guess it would be Europe because they love electric over hydraulic steering.
