Wow, those buses must be made of adamantium!

The comically large chainsaws on the front have proven remarkably effective, with proper maintenance of course.

Not mentioned in this fluffy article is that the buses will have been acquired (possibly using loans) from China and were made possible by the massive investments in green tech that only China is bothering to do. Meanwhile, off the coast of Senegal, Chinese industrial fishing boats are pillaging the seas and depriving local fisherfolk of their livelihood. So it's a mixed bag, but the electrification of the world's urban transit is a massive deal and China deserves credit for this.
