I have two points.

The first one is your body's schedule. I also have a job that requires me to be at work at 5:30am. My body wakes up every day at 4:30am. This includes Saturday and Sunday, but I can usually go back to sleep. In order to keep my sleep patterns the same, my body wants to go to sleep every night at 9:30. This includes Friday and Saturday nights. I do take naps on the weekends to help me get to/recover from the races. However, Sunday night is horrible to try to get back on schedule.

The second point is simple efficiency. Why would I want to go back to a 56K modem, when I can have DSL. Why would I want to go to a track that can't start on time, that drags the program out, and takes endless intermissions. When I can go to a track that starts on time, runs the program efficiently, and has a set intermission. Once you see an efficient program, an efficient program only makes you mad. If the track must have an intermision, it should be a timed intermission. My favorite is when the announcer states, "We are now going to take a 10 minute intermission", and then puts a ten minute counter on the lap board. When the clock reaches zero, the main events roll on to the track. Once I have seen this, why would I want the endless intermission that many tracks prefer.
