What Mr. Tacx should do to improve my toy.

There's much to say there...

The software and its menus are not that bad, but not as intuitive as they should be... Particularly, when one wants to choose a new route, or set his rider profile...just have a try at it, you'll understand...
The long names of your opponents are overlapping each other in the menus, so not that easy to choose one...

Why don't they make some serious map...
the virtual "worlds" are in fact virtual "kindergardens"... you've got three "maps" there, with only one of them with enough roads to allow you to actually create your own runs using the steering frame... The two others maps, basically, will let you pedal around a tiny island during 20' and you're done... would'nt be the opportunity to ride against other riders on those virtual worlds, it would quickly get boring (which is the inverse aim, I guess, of that kind of device...).

A good idea could be the release of a map editor... apparently, Mr. Tacx doesn't want to (Frankenstein syndrome ? the fear its toy could live by its own...)

The RLVs :
they are filmed from a motorcycle in real life. Several drawbacks are linked to this method of making the RLV :
-In real life, you're forced to slow down at road jonctions and stop signs, so the RLV movie will slow down proportionnaly to the slackening of the motorbike used to make the RLV.
So, while riding on your RLV, you're going full speed then you arrive to a stop : although your speed (as displayed on the screen) stays high, you "visually" see yourself slowing down... no matter how hard you go on the pedal... (of course the faster you go, the faster you'll get out of the "slowing down passage" but you'll still have that feeling of a "speed drop" compared to the speed you were going just before...).

-In real life, when you're climbing or going downhill on sharp turns, you don't look in front of you, but 4 to 5 meters ahead in the curve (or else you'd quickly hit the planet). When making a RLV the camera is fixed to the motorcycle, so what you see in a sharp turn while riding your bike on RLV, is just the first meter in front of you... NAUSEOUS....
I think a good idea for Mr. Tacx for doing his RLV may be to use a camera as the one skydivers use, it is to say, fixed on the helmet of the rider.
Besides, doing so, the RLV would seem more realistic.

No lap function, what you can do with a tiny bike computer, you can't do with the 3 ghz PC powered Fortius... It could be notably useful, to work out with a lap function while doing intervals on the velodrom.
