Inactive Kers

All cars who don’t set up should not be able to use kers! It ruins races as they just boost around and messing up the races of people who cared to set and show up!

Yeah completely agree. If/when they turn up to the race then they should be allowed. 

I agree, 

Or maybe they only get the lvl 1 usage... I think the host should be able to enable/disable this, but otherwise I agree.

and even better they should use KERS specifically for you so that you always end up in the DRS))

Should just remove keys indefinitely and just leave drs, for me thats more realistic as depending on ur level keys is better or worse than others .
