Honda is perhaps the most frustrating engine provider I've seen. They keep getting in and pulling out, especially when they're starting to get the hang of it. They were very successful with McLaren in the late 80s/early 90s and what do they do? They pull out. They get back into F1 in the late 90s, run a couple of years, get nowhere and pull out. They get back with McLaren for a couple of years and are shit, and the deal ends when it should start to bear fruit. They get with RB, win a championship, and pull out.
JFC, just shit or get off the pot.
