So, how do you increase your rep? You do that by achieving smaller in-race achievements that are thrown at you by your ‘Engineer’ at random.
All of this sounds quite exciting and while the objective is to throw in a sense of urgency and increase tension, it just ends up feeling quite dumb thanks to the random nature of it and frankly it is all a bit odd.
For example, your engineer will ask you to hold off on going hard and keep an eye on your fuel gauge even when you can clearly see you’ve got more than enough for that race and a couple more laps of the next race! The engineer will also say things like ‘Your lap time is a bit erratic’ even if you’ve been consistent but just had a stop to change the tyres.
After a point you just yell STFU and carry on with your lap. There’s no penalty as such if you don’t complete these ‘side quests’ so the game knows they’re a bit iffy as well.
