I had only been thinking the learning software of "learning-o-Mat" to buy, but this did not please me, since according to the description no comprehensive statistics are included in the program. Quite different with "go4drive" I have an update service to September 2015 (when "learning-o-Mat" übrigends also) and a really good representation of a statistic. The different predefined learning modes offer learning for everyone a good way. What I still lack was some sort of account / account management, so that more than one person can use the program on the same PC without the statistics are distorted.
