I agree with you on the approach you take - deeper lots and buffering - but I still think they can be avoided in most situations. Whether they will be avoided is another matter.
Restricted access county roads are a problem here, too. Come on, is it really that much of a problem to have driveways on a road with 3000 cars per day? If they can't live with that, how about at least having more frequent road intersections. For more busy streets where access would be problematic, other uses might be best on the collector road. I don't mean just commercial, industrial, or multi-family, but also parks, storm water facilities, etc.
Double frontage lots and frontage roads are just a couple pet peeves.
