I did a cross-country trip last month, from LA to Savannah GA. Pulse and Glide the whole way. There were two of us driving. We checked one segment and we were doing about 2 cycles per mile, so the 2,500 mile trip took about 5,000 P&G cycles. Yeah, that's a lot. We also got 63 mpg crossing the country in a brand new Fiesta.
P&G works.
