Because vehicles are expensive and people don't replace them all that often? Affordable, capable EVs are relatively new and being competitive with gasoline vehicles doesn't necessarily mean they're so competitive that it makes sense to prematurely replace a working gas powered vehicle.

Longer term though, EVs replacing gasoline vehicles for those kind of use-cases is exactly what we're going to see. In the US, the postal service intends to start deploying tens of thousands of EVs over the next few years as they replace older gasoline powered delivery vehicles. The economics do apparently work out and pass the sanity check, just not overnight.
