So, I know that in a regular car, is is a BIG no-no, but I do it in my Fusion Hybrid from time to time.
First, let me ask does anyone know if the Hybrid drive train actually has a gear that switches to go from R to D? Or does it just reverse the current through the Traction Motor? If there is a gear, I will immediately stop what I am doing, but if it is just current, then there is no harm.
Now for my issue,
When I back out of my driveway in the morning, I don't always wait for the car to stop before going from R to D. Now, I'm not going SUPER fast, usually under 5MPH when I do, but I have noticed something really concerning.
My driveway is rather long, so I get moving when backing out of it (15MPH or so). When I get out onto the street, I hit the brakes, slowing my vehicle (regen, not service brakes), then switch from R to D (with my foot still on the brakes). The moment I do this, all brake power goes away, and I continue to roll backwards in D as if the vehicle was in neutral with no brakes. If I take my foot OFF the brake, I stop quicker than with my foot ON the brake.
At my house, this is not a concern as I live at the very end of the street, and I know no one is behind me. But I have had this happen in a couple situations where it was almost dangerous. I honestly feel that a vehicle should continue to brake at the same rate, regardless of what gear its in, or which way its going.
Anyone else do this and notice something like what I am describing?
