Adherence

Mixed-mode commuting that includes cycling is associated with lower risks of all-cause mortality, cancer incidence, and cancer mortality compared to non-active commuting.

If you can't cycle the whole way, try mixing it in. This study links mixed-mode commuting (driving + cycling part of the way) to lower death and cancer risks. It didn't help as much as pure cycling, but it's still better than driving alone. Walking as part of a mixed commute didn't show benefits.
