The main operating cost of running a bus line is the salary of the bus driver. It dwarfs vehicle maintenance cost and petrol. The VLR has the ambition to run autonomously eventually. Autonomous buses are quite a bit further into the future.
Not really because buses get stuck in traffic all the time because there’s a point where they need to share roads with cars. Once you spend the money on segregating buses entirely, you’re at the same level as the tram line.
Also, because of the expensive infrastructure that can only be used by trams, there’s a permanence there that prevents future politicians from ripping it out to put more cars on for a quick political win with drivers.
Going back to point 1: having a line means that any route needs to be properly planned because you never have an escape hatch of “just stick them on the road.” Example: where I live, the council installed a bus lane and a cycle lane. Where it pinches in (planning fuck up), it dumps all the traffic into a shared route with 2 roundabouts and 5 exits, each with an insane amount of traffic coming to or from them. Buses that are forced to use that route are always late. It takes me just as long to drive as it does to take the bus, faster if you factor in me waiting for a late bus.
The solution to that is dedicated bus lanes, which are quite common in some cities. Usually they allow taxis and emergency vehicles as well.
Trams here in Berlin share the street with the cars on some streets. So, it's exactly like a bus that can get stuck in traffic (and they do). Dedicated tracks are also common but they take up a lot of space and it's expensive infrastructure to install. Mostly trams are limited to the former East Berlin, though they've started to spread to some parts on the west side.
With electrical buses and bus lanes, you get most of the advantages of trams. There are probably still some advantages to dedicated tram lines. But they are expensive to install. I'm not sure it's worth the investment.

Like many tram lines, CVLR is being laid in-road and not segregated. In fact, while not mentioned here, the it's 15 m turning radius is so important is because it's planned to traverse roundabouts in-lane.
