Hypermiling is a well-known driving technique to maximise fuel efficiency. Essentially, if you're a 'hypermiler' you will always seek fuel saving ways of reaching your destination. If it's a short drive, you may walk or use public transport, but if it's a longer one you'll pull out all the fuel saving techniques we've listed above.
Hypermilers adopt proactive techniques too, such as reversing into parking spaces, so they're facing in the right direction when they next come to drive, and facing their car into the sun on colder days, so they can avoid deploying energy to their heated windscreen to defrost any ice.
