Solo motorbike trip across Vietnam: 1 in 2,900 chance it kills you

~350 micromorts. Like 18 days of heli-skiing, or 5 nights in hospital. Estimate.

Mortmeter: Worth it. Unfiltered freedom on two wheels beats a sterile tour bus every single day.

Assuming: Riding 2,500 km over 30 days along the classic north-south route on a semi-automatic scooter.

How we got this: Western motorcycle baselines sit around 7 micromorts per 100 km, but Vietnamese traffic dynamics and tourist crash rates double that figure to roughly 14 micromorts per 100 km. 25 units of 100 km multiplied by 14 micromorts per unit equals 350 micromorts.

What gets you: Sleeper buses overtaking into oncoming traffic, Gravel and washouts on mountain passes, Limited trauma care outside major cities.

Cheaper version: Ditch night riding and buy a certified full-face helmet to slash your acute risk by roughly 40%.

Sources and method: how Mortmeter prices things, and the Atlas of measured risks.

More priced risks: Sharing a bottle of Flor de Pingus, Riding Polyppen at Bakken in Denmark, Eating 2 whole pizzas, Drinking a bottle of red wine, Winter bathing in the Øresund, A week of off-piste skiing, Getting LASIK eye surgery, Texting while driving on the motorway.
