I drove a new BMW 7 series a few weks ago, full of toys and it was the most annoying thing to hit the gas and wonder if the engine fell out, I understand the point you are making about the driver retraining to its system.
But the point is technology is supposed to help the owners and their expericance of it not hinder it,.
Never mind for the companies to make stupid excuses of a fully engineered product.
they should have labeled the US version the ES 330B for beta.
Easiest way around this it to get a Canadian ecu and pop that in instead as they do not have the issues.
