Because people don't want to ride in poor weather? Because the terrain is inhospitable to their current fitness level? Because the terrain is inhospitable to any fitness level? Because they may only have 45 minutes to ride and want to spend the full time riding? Because they live in an area with a lot of pollution? Because they have medical issues where they worry about getting stuck away from their home? Because they just like tech or just don't like being outside?

There are plenty of completely legitimate reasons.
