If you ban cars they will be even more dead.
Not true. Go to Leiden Netherlands and see how economically vibrant a small city can become if it incentives efficient land use and limits traffic in city centre in favour of pedestrian paths an public transit.

I'm not sure I would say the latter change, which was recent-ish, made a big difference versus just the general cleanup of the inner city (better train station, spruced up Beestenmarkt square etc).
One of the best ways to eliminate left turns is to replace four way intersections with roundabouts. This has the advantage of working even where there isn’t a grid to facilitate the “3 right turns” strategy.

I'm a little skeptical that it would be safer for pedestrians and bikes. Bikes need to merge with traffic already in the roundabout instead of simply going straight through an intersection, and pedestrians would need to always check for oncoming cars rather than being able to mostly rely on lights telling them when they can cross. But then most of my experience with roundabouts is with large, multilane roundabouts so…
The bike path crosses before the point where cars merge in, so the driver's attention isn't split. Also, it may not be obvious from the picture, but the car lanes are raised to the level of the bike path where they intersect.

Are there any stats that left turns are/how dangerous? Here most (at least the majority of media reports is about) cyclist die when a truck turns right.
The biggest problem with right turns are: 1. Free rights a uncontrolled right turns that don’t protect crossing cyclists and pedestrians through time based segregation. 2. No physical/grade segregation. Cyclists become invisible in blind spots during right turns because intersections are terribly designed to support anything other than cars. A well designed intersection puts cyclists in front of cars where they are v…

But people don’t know how to use them and just make it a free for all. Look no further than the Boston metro area for how this actually shakes out.

If it's the urban core busy city center where there are skyscrapers right up to the lot line, there's no room for a roundabout unless you're willing to make 'round a bumps' or carve some footprint out of the buildings at traffic level.
If it's the busy city center where you've got four lane surface streets intersecting with each direction having two straight through lanes, one right turn lane and one or two left turn lanes, a roundabout is never going to manage that kind of throughput by forcing all those people into a single lane to get into the roundabout at low speeds.
You may have fewer collisions, and of course very few of them will be during left turns, but you'll also reduce the utility of the roads connected to the roundabout, which will likely move traffic to other roads. Also, a collision in the roundabout stops the roundabout, which makes it hard to respond if people are injured or vehiclea disabled.
Traffic signals with 'protected' lefts don't stop people from going against the signal, but they do stop a lot of people from trying to make a gap that they really shouldn't. Sometimes a three-way signal timing pattern is appropriate; for the main direction, opposing traffic has greens for straight simultaneous (with cycles for protected left if appropriate), and for the other direction, each side gets a green for straight and left one side at a time.
