If that was the case, then Lewis would never ever said he might sit out free practice.
He might be saving, to make sure he still has engine(s) left for qually and / or races alltogether.
re-using an engine vs installing a 'fresh' one could define the outcome of the championship in the end, after all.
Still, the margin is too small to say he's really taking an effort to save, indeed.
He might be influenced by the past events though, so his focus might be 'off'. Which is not good news, as last weekend he got 'complimented' or it got noted they haven't
seen him 'as focused' as he was the entire season until that point.
Please lewis, jump back even stronger.
