In "The cartesian product of a certain nonmanifold and a line is $E^4$" (R.H. Bing, Annals of Mathematics series 2 vol 70 1959 pp. 399–412) Bing constructs a nonmanifold, $B$, such that $B\times \Bbb R$ is homeomorphic to $\Bbb R^4$.
Is there a space $X$, not homeomorphic to $\Bbb R$, such that $X\times \Bbb R $ is homeomorphic to $\Bbb R^2$?
