Converting braking into electrical energy is a no brainer as we all need to brake, and quite often if we live in the city.
But converting bumps and corners into electricity? Yes, but I just do not think of it as cost effective.
Cornering will likely produce zero, as the roll of modern vehicles is practically nothing, unless we are cornering fast enough to go into a tail skid.
Bumps? That depends where we drive. Most towns and rural roads are not rough enough, unless all that stimulus money obama ear marked for infrastructure gets lost in the wrong pockets, then they will get rougher with time.
I think the idea is some greenie’s silly fantasy.
You must live in the south. And somewhere flat.
