You just don't get it at all, sorry - If your "performance" vehicle doesn't have adequate cooling system, your option are:
1 - Sell it and buy vehicle that works for your driving requirements
2 - Modify it (slap some after-market parts) to make the under-performing system actually do the work
3 - If you are a complainer type, write a letter to manufacturer of you vehicle and ask them to fix the problem and go on about and how you are going to report them to government as it almost killed you, there should be recall, millions of $ in lawsuits, blah blah blah.
4 - Lane-split and if you get caught, pay the price.
In terms of engine cooling - you chose crappy vehicle for your commute, and you expect others to make concessions for you? - and "others" in their wisdom choose to drive vehicle that won't overheat in a slow moving traffic. They should take a bit of time to make room for you? Sorry - I have to repeat it - you don't get it at all.
Now, forget your under-performing vehicle that cannot keep its cool, and focus on the fact that smaller vehicle such as a motorcycle takes up way less room on the road, and it is appropriately sized for single occupant vehicle. If more commuters switched to motorcycles, it would benefit everyone by easing congestion, and with added benefit of requiring only a fraction of parking space, it is a win-win combination - and with that logic, it is a positive thing, and everyone stands to benefit from more bikes on the road. With that logic, government could look into ways of encouraging more people to switch to motorcycles, perhaps allowing lane-splitting...
If you think you should be allowed to lane-split or jump the line because you didn't chose your vehicle wisely, opt for number 4 and don't expect any sympathy from anyone.
If you make a case that motorcycles benefit everyone, you will get sympathy and respect, and perhaps more.
