Since you have a Mk1 I assume you've been around for a while. Anyways the car product is EOL and the guys are working on projects that actually pay money. Since it does share code with other current (i.e. paying) projects we can hope they will appear in a future release of the RioCar software but when they get time. Remember they're probably using the software themselves so it is in their interest to code to some extent

Be patient and don't hassle the guys please... They're still here and they still provide us with tons of useful info to go off on our own hacking projects.

Oh and ... "it's released when it's released" is the standard line around here if you haven't been reading.
