S1: Lotus, awful struggle in the beginning playing on expert thinking I could manage with no assists. Came good near the end, winning races (with assists & a lower difficulty).
S2: Red Bull, breezed to the both WDC & WCC titles.
S3: Ferrari, copy & paste Red Bull dominance.
S4: Red Bull return. No interests during season, other than Lotus. Post Abu Dhabi, agreed a return to Red Bull & ready to conquer expert.
