Read a book, read latest copy of Sport Compact Car, have a snack, have a beer, put bob back onto 3x speed every 20 minutes or so as he pits.
Finally starting to get bobs skill up. One hint, dont put him in a slow car his skill wont go up very much. Had him do the roadster endurance and his skill didn't up. Had him do the El Capitan and NY endurances which are shorter and his skill went up a bunch. He did the El Capitan in the Ford GT and NY in the Viper which are of course much faster than a miata.
