I know this threads a couple months old, but I'll resurrect it for a minute to throw my support behind adding voice controls to toggle between acceleration modes. Or a menu shortcut would be good too--I think someone has suggested tapping the speed readout to switch between chill and standard mode. This is the main thing I find myself wanting to do that requires me to take my eyes off the road. I mostly drive in chill mode, but occasionally I'll be in a situation where I want to pull away from a stoplight quickly. I've even thought about buying the S3XY buttons from Abstract Ocean to add the functionality myself, but so far I've balked at the high price of those.
