Do you really know what you're talking about ? Or maybe you're making a reference to Russia GP when Williams stopped Kubica race to ''save parts'' LOL...who does that....??!!
1- Kubica receives a new gen front wing - instantly faster than Russel
2- Team changes the wing for an old version without advising the driver
3- car changes behavior because of no2 and Kubica crashes
4- Kubica is racing with last winter specs car
What do you expect ?
Williams sucks big time and treats Kubica very unfairly, at least he gave back what they deserve by announcing his end of agreement with Williams for 2020 which puts them in a hard spot to try to jack up Lafiti's fee for driving their car...
Williams is a managed by bunch of idiots even Russel is starting to loose patience
It's the only team when 2019 car perform worst that 2018 version which was already shitty...
It's called backwards development
