Suspension of Disbelief: HIGH-RISE (2015)

Why wouldn't the futuristic (circa.1975) architect take into account the need for yuge parking garages?!?
No carparks in 1975?
What were they thinking?

Aside from this glaring omission of logic it's really a good science-fiction, movie, imparting, a retro futuristic look and I recommend it highly. ★★★☆
