Where in the world did this boost mode feature come from and why is it here? This could not have been on the top 500 list of things being requested by users. Racing is the one area where the goal is to achieve a level playing field and not have someone blow by you at the end of the race doing an extra 200 watts they aren’t capable of doing in real life.
Seems like Zwift is trying to turn this experience into Mario Kart. The time spent developing this could have been better spent on updating the UI or allowing a save without exiting the game.
