A typical European car is parked 92% of the time. It spends 1/5th of its driving time looking for parking. Its 5 seats only move 1.5 people. 86% of its fuel never reaches the wheels, and most of the energy that does, moves the car, not the people.
Sound efficient?

Dear Britain, it’s now clear: 20mph zones save lives & don’t slow traffic. Implement them.— @sadiqkhanlondon.bsky.social.
“Despite what detractors might claim, 20mph speed limits haven’t actually made journeys slower because journey times are largely dictated by junction delays, not vehicle speed.”
