In simple terms, I take this to mean don't run the car hard right after you leave the garage and don't run it hard on the way back into the garage.  |
How would one perform those procedures in an urban environment where some of us are only minutes from highways where there is no sufficient time to warm up and cool down. Seems like a waste of gas and defeats the purpose of higher fuel efficiency if you have to ride around the block a few times to cool off the turbos.
