When I was TDY'd for many months to SFB they made me do the rental car reserve thing to PIE 4 or 5 times. Every evening when I got back to PIE I called scheduling and told them I was to fatigued to drive back to SFB and to give me a hotel in PIE. To my surprise they did it promptly, took me off my trip for the next day and pay protected me for it. No call ever from a chief pilot and the hotel was provided in 15 minutes or less.
I was TDY'd and didn't care whether I made it back to SFB in that case. I think most guys here have "get-home-idus" and would rather drive home fatigued and sleep in there own beds than be in a hotel. The company knows this and takes advantage of it. I too think if every pilot would start calling in fatigued after a day of 3hr drive followed by a 16 hr duty day followed by a 3 hr drive, that "reserve for the whole state" thing would start to go away.
