lets look at the facts,the ryanair 737 burst his tyres on landing and intially veered left before trying to vacate on the high speed exit at KC,where does D1 come into the incident.When you are cleared to D1 that is the furthest you can go, your clearance limit, if you are unhappy with D1 you can hold back from the holding point,as some acft already do to get a run up for the crossing, D5 may be accecptable on a quite day!!!.All you have to do is ask.
