Is the look left/look right feature in GPL useful?
Yes, I’ve used it, and I find it very useful for determining the location of other cars in passing situations. It takes some adapting to get used to it, and I’m still adjusting since I put look left-right buttons on my wheel, but I think it is an almost essential feature. Note that the implementation has changed slightly from the demo. The original intention was that it would be used to see if the track was clear before you re-entered after a spin, but the beta team asked for modifications that would make it more useful when dealing with traffic situations. Also, I find that having buttons for these functions on my wheel is really essential; it’s too distracting to take my hands off the wheel while at speed just to glance to the side.
