Better definition of annual mileage per year of age

[romainsacchi]

Currently, it is assumed that the annual mileage is constant through time.
This assumption is quite important as it influences the lifetime-weighted electricity mix used to charge batteries or produce hydrogen.
But we know from data (for example here) that the annual mileage goes up after the first year of use, culminates between year 2 and 8 and slightly fades until the vehicle disposal.

It would be much better to adopt such distribution.
