Yes, that does mean only 40 minutes of driving time unless you're charging during practice. How many minutes driving do you get at qualifications? Would you start match 2 with the same battery as match 1? Why would it differ at practice?

In short, change batteries frequently. Put the one just used onto a charger very soon after it comes out of service. Do not let the last batteries of the day wait until your next meeting to get their electrons jolted back into shape. Think of driving practice as competition practice. Those pit crews at NASCAR never just go through the motions.

From another thread, for consideration in this one...

I do very much agree with timing practice sessions. It helps reinforce how much time is actually in a match as well as protecting batteries. The "practice" option in the operator interface is great for this.
