We show that if$G$is an anisotropic, semisimple, absolutely almost simple, simply connected group over a field$k$    , then two elements of$G$over any field extension of$k$are$R$    -equivalent if and only if they are${\mathbb A}^1$    -equivalent. This has two important consequences. First, the$\mathbb A^1$    -singular construction${\rm Sing}_* (G)$cannot be${\mathbb A}^1$    -local for such groups. Secondly, the${\mathbb A}^1$    -connected components of a semisimple, absolutely almost simple, simply connected algebraic group of classical type over a field$k$form a sheaf of abelian groups.
