The problem with this is that following this practice means my tires are howling around that right hand turn. I typically do the downhill in 4th gear in DCO. This provides enough braking that I can negotiate the turn, at the expense of some tire wear. Also, if there is a car sitting at that intersection, the driver may get a bit wide-eyed as some idiot comes barreling straight at him at speed in his Sportwagen.

So the question is do I consume tire or brake pads/diesel? I suspect it probably makes sense to lean towards braking, especially since I have a very efficient engine that absolutely loves to pull hills anyway.
just fall back to EV mode
