When driving the bakerloo line when it is raining. Rain appears to be wiped when looked from the outside but from the inside, no water is visible on the windscreen.
leave the wipers off a bit and it will. I thought this and switched of the wipers but you soon need them on.
Same here I did the second scenario from Queens Park to Harrow and back in the rain and only needed to use the wiper once!!!! There wasn't more than a few spots of rain on the windscreen even when stood at station stops.
This appears to be a bug if you switch to one of the external cams and back to the cab. If you get out of your seat and sit back down, the rain will start to magically appear again on the windshield
