Great, those are obviously unsafe on the freeway for a thousand reasons, so let’s just whack those on dedicated roads. And since only those buses go on the roads, they could be steel wheels on steel road for extraordinarily better efficiency, and obviously steel is pricey so we’ll just limit the road to two ‘rail’ like lengths. Dedicated lines can be electrified for more efficiency, build some dedicated bus board/alight platforms, a bit of signalling to prevent crashes and avoid building excessive rail, extensible for varying passenger numbers, and BAM, perfect project.
