It is only three, max four hours, on a motorway. Hardly excessive, especially on a lightly trafficked motorway.
What is the maximum driving time that you consider safe?
Personally I will only drive for about 2 hours max without a break for the loo and a coffee or similar. So for a journey of that length I would stop either once for longer or two shorter stops.
There is a very good reason movies are typically around 90 minutes to 2 hours long, and why the same applies to school lessons and university lectures, seminars etc - that tends to be the limit of people properly paying attention.
