I totally understand that, and I've seen it plenty. In fact I've been on both ends of that, giving and receiving. I'm relatively fast, but not alien-fast, so I'm usually faster than at least half the people in any race, but there's almost always 2 or 3 in the front that I can't catch at this level (A to A+). I've been aggressively pushed off course by some fast guys desperately trying to gain positions, even when I wasn't defending very hard. I've also been that guy, started pole or top 3 and get punted immediately. I try to be patient when passing others on the way back up, but the problem arises when those guys don't want to concede the position by any means necessary, even if they are clearly much slower and have less control over their car. There was a guy yesterday who was a couple seconds per lap slower than me, and at first he was defending fine, but after 1 lap he was weaving and blocking at every chance, slowing us both down and eventually I accidentally ran into him on the inside when trying to overtake, because he was moving erratically and unpredictably. I apologized but he still called me dirty. Stuff happens, and it's hard to have a clean race with drivers of all different skill levels, so I sympathize, but it's still frustrating.
