I have had zero issues trusting the RL on ice glazed roads(I-80 60 miles west of Chicago runs east/west through open cornfields, and drifts and ice glazing are a regular occurance). Last few winters on numerous occasions I had domestic 4wd trucks(chevy's, fords, etc) in front of me & behind me, going the same speed as I was, spin out, and end up in the ditch as I just cruised over the same ice patches never losing the trucks footing.After reading this article, I am still confused about the VTM-4 system. I am worried about driving on icy highways – the kind with icy patches interspersed with snow covered patches. The driver can only engage and use the VTM-4 system at very low speeds (for getting unstuck or for preventing a hang-up). But on the highway, its impossible to lock it in and go 60km/h say, if the road is a complete skating rink. Can I trust that the system is effectively and automatically managing torque?? ... I hate having to trust that a computer is doing this for me! I'd rather either have a subaru AWD system that I know is on all the time or an old fashioned lever for 4WD hi/low. I bought the Ridgeline without doing my homework. It's a great truck in every other respect and fits my needs perfectly about 95% of the time, I'm just a wee bit uneasy about traveling at highway speeds in crap conditions. Any input on this is greatly appreciated.
