I will never believe someone has a bad computer. Why? I'm yet to find someone in the community who has a worse PC than mine. I play in 30 fps and I complain about lag all the time yet I don't put myself in a position where I'm speeding like a madman and when things don't go my way I use some excuse to shrug it off.
I have a rule of my own and it doesn't matter if desync played a huge part in it. The rule is that if I crash, I roleplay, no matter the circumstance. I'm extra careful when driving due to my lagging as well as knowing someone might be reckless and if I collide with them then it's my fault because I should've known better.
