I managed to do a perfect lap in the fiftees on that race lol, made a nice change to get that little noise an the words pop up below Zone 55

As for the speed thing, it does keep getting faster, in fact in the sixtees i've started to notice a little more bounce in the walls, several times i did a bit of a pinball impression, one wall to the other (though some of that was to do with bad line correction lol) but indeed it keeps getting faster
