The rolling tangent space, a forgotten vision on geodesics and parallel transport?

Given a submanifold $M\subset \mathbf{R}^ν$, a curve $γ:I\to M$ and tangent vectors $v$ along $γ$, we roll the tangent space along $γ$. In doing so, we get an imprint of $γ$ on the tangent space, as well as an imprint of tangent vectors. We show that $γ$ is a geodesic on $M$ if and only if this trace/imprint on the (affine) tangent space is a straight line and that $v$ is a set of parallel vectors if and only if their imprint on the tangent space is constant. In other words, in the view of the imprint on the rolling tangent space, a geodesic is a straight line, parallel transport is indeed that: parallel transport, and the covariant derivative becomes the ordinary derivative.
