Setting the objective function is often the most challenging. Different teams may prioritize different objectives and often it requires balancing multiple at once! For instance, how does a company think about the types of user engagement and long-term metrics like retention? A model optimized for clicks might be worse for retention in some cases, but not in others. Ultimately, we A/B test to find out. Surprises and counter-intuitive results are common!

I’d expect long >300km trips to be <5% of in total transportation?
