Rear-ending is always the rear car&amp;#x27;s fault and it&amp;#x27;s always their responsibility to leave enough space and time to react and stop safely.&lt;p&gt;If the lead car braked when there was no reason or danger, that driver might also be cited for recklessness or some such, but a rear-end collision is always an error by the rear driver.</text><parent_chain><item><author>spike021</author><text>&amp;gt;The rear-ending problem will be solved as automatic emergency braking becomes standard on cars.
