My pet peeve is that there is no hybrid bike/transit routing option. If you choose transit, they assume you are pedestrian. Maybe the option is there and I just have not found it.
Citymapper at least tries, but is still bad for bike+public transport.
I look at the options that Citymapper gives and then have to recalculate the route, in my head, correcting for wrong decisions about where I'll have access to a bike.
(Yes, it'll be quicker if I cycle my own bike from my home to the nearest station. No, I won't be cycling a hire bike 111 minutes away from its closest docking port.)
