But why? He’s shown before in the Williams that he can perform with a decent car. The AT is simply shit, Tsunoda isn’t doing much better and it’s not that he got to where he is without a few fuckups/meltdowns of his own.
EDIT: as burn points out below, he didn’t race for Mercedes but for Williams, I’ve updated my post to reflect the correct team
The only reason I can think of, is that they want a benchmark to test Riccardo against. To assess their options for the main team for next year.
Or to install Riccardo as the bench mark for their talents in the feeding series.
