  While engaging with the unfolding revolution in autonomous driving, a
challenge presents itself, how can we effectively raise awareness within
society about this transformative trend? While full-scale autonomous driving
vehicles often come with a hefty price tag, the emergence of small-scale car
platforms offers a compelling alternative. These platforms not only serve as
valuable educational tools for the broader public and young generations but
also function as robust research platforms, contributing significantly to the
ongoing advancements in autonomous driving technology. This survey outlines
various small-scale car platforms, categorizing them and detailing the research
advancements accomplished through their usage. The conclusion provides
proposals for promising future directions in the field.
