The following are all ~ 1 in a million chance of death, or 1 micromort:

Travelling 6 miles (9.7 km) by motorcycle

Travelling 17 miles (27 km) by walking

Travelling 20 miles (32 km) by bicycle

Travelling 230 miles (370 km) by car

Travelling 1,000 miles (1,600 km) by jet

Travelling 6,000 miles (9,656 km) by train

But switching from car to bicycle for short trips still increases life expectancy due to health effects.
