Looks cool, lighter, which means less frequent tracks repair, however it takes more electricity for its air conditioner, the grid has been upped to accommodate it already, although it is more spacious and lower to the ground for easier accessibility, that said, i like neither that the seats are facing each other, nor the absence of single seats. 

Besides the point is that the public transit is an essential service owned and paid for by the public, one way or another, for public need to use it, thus making public pay to use it is obscene to say the least. i think it should be on donate what you can basis, after all it costs more money to charge people for using the public transit than making it available for free, same as the public parks. 

The officials in charge can organize regular fundraising campaigns, such as hospitals do regularly, and can lobby for its budget with the government process, same as police and firefighters, therefor to charge the individual citizens to use what is inherently public and for the public's essential interest is not correct regardless how it is explained to be justified.
