I once touched an experiment in the form of a metal wire coil where each alternative loop was hot and the other cold. It felt superhot instead. I feel like this would be similar.
I'd also allow people to pass if they come up behind me, but if I'm going slower than general traffic I'm not going to randomly slow down even more to piss people off, that's just silly.
The best bang for buck Steam purchase I've done is Halo MCC for 39,99€. Five great games plus Halo 4.
