I prefer long drives, 60% of 27k on ODO was to my home town wich is 710km. Usually take two breaks of 45min each as i got a kid who is 2year old now. Prefer night drives because of less disturbances both on road and in car. Maintain 90-100Kmph on four lane HW and 80-90 on two lane HW. Music depends on mood (usually switched off). It is difficult to maintain 80Kmph on four lane HW, feels drowsy and even FE drops(my observation). Last trip to home town was complete night journey (2000 to 0700) with four 10min breaks for LC, fuelling and nature calls. Average speed 68Kmph, FE20.1(MID) Kmpl. Best thing to avoid sleep is keep sipping water and not delay attending nature calls.
