More consideration required for ♿
A wonderful collection of British motoring history. Both the main museum and collections building are reasonably disabled friendly, once you get there. Unfortunately today there was no blue badge parking. Usually one end of main visitor car park is allocated and signed. Maybe the signs were the ones face down on the ground. If so ( as usual for last 8 years) the spaces are standard width with no extra width to open car doors fully, essential if you are a wheelchair user and need to assemble your chair to leave your car. I have a boot scooter and need to open car door fully to exit car. I found a space elsewhere in the car park with crosshatch bands both sides of bay. That's how your " blue badge parking" should be.
Could do better if you tried. I note you seem contemptuous of people with disabilities from another review. Get a grip!
Oh, as for the long steep hill between car park and museum.... I had powered mobility scooter. I have been a wheelchair user and would not attempt it alone! To the museum would be pretty fast. The return, exhausting.
