I'm happy with the 7.1 improvements, but I believe the MS intermittent wipers will never be as good as what I had with my former Lexus -- primarily because the Tesla has only 2 physical intermittent settings (like my MBZ used to have), whereas my Lexus, once placed into intermittent mode, then had a secondary physical ring on the same stalk allowing variable control over the sweep frequency. No matter how Tesla reprograms it, IMHO, 2 settings will never be as good or please as many owners, as allowing the driver to just refine intermittent frequency for their particular circumstance like my Japanese Lexus provided.
I appreciate PadD's suggestion of adding something to the UI, but for me, that's a horrible workaround -- needing to touch the stalk to turn on the wipers with one hand, then seek out a setting to change the wiper frequency with the other on the 17". I doubt I'd use that very often because it's just too much to deal with.
