Why do we see those empty starting pens/areas?

Why do we see those empty starting pens/areas?
Why couldn’t I stop by and see what events might be starting from there next?

We already have a climb portal that works a bit like this. Well obviously this would require much more time for rider to choose but if you stop by. Then you could take the time it takes to choose. If you won’t find anything nice just continue your ride.

Starting event (ride/race/wo) straight from there could also be saved all in one file, wu + cd and possible more than one event if you decide to take another one after first…
