I think it’s a great idea!
Hiding the boost would make races more interesting and maybe also avoid that managers leaves the race early. I mean (I did it also) if you see you had use all your boost and your opponents are still full, it’s demotivates you.
But what I would like to suggest is a counter which counts how many times your opponent did use boost.
I mean not the amount just how often they pushed the button.
For example:
Guy A pushes boost and hold it for 10%….
Guy B pushes boast and hold it for 1%
Both counters will say they used boost once, but you don’t know how much they use.
This could be add a new tactical element to confused your opponents
I agree to you. Your opponents may be confused. But, after all, this is only meaningful in close races, not in races where the managers' car are far too different to others in terms of race pace.
On the other hand, if the KERS usage is still there, managers can choose their time to deploy the boosts more correctly (maybe turn it on together with the DRS, etc). In my opinion, this one can become a league rule.
When I use the KERS, it currently just not enough to charge through your opponent (i mean, especially in low level, it doesn't help you a lot in terms of overtaking or race pace). So, it can be a good idea to increase the strength of the KERS (if you watched F1 or play F1 game, you know that the ERS can improve the car speed by up to 20mph at maximum use, which is even bigger than DRS). And, as the ERS is used in a whole race and the KERS is non-rechargeable, the strength of KERS is really important, especially when the Technology site in the HQ only increase the amount of boost you have, but not its power.
