I'd rather drive a Lada with the Canadian, British and American flags on St-Jean-Baptiste day in Québec City than own a Prius. It runs on battery power at very low speeds only, can't be recharged using a plug (at least when stock) and at highway speeds (which where I live, represents 99% of driving), you only end up hauling an extra drive system.

Current hybrids are an attempt, but plug-ins are certainly better thought out.
