I tried Waymo when I was visiting LA a few months ago. Genuinely terrific stuff.
I do not trust Teslas one bit though.

Can this be solved with just cameras, or would this need additional hardware? I know they removed LIDAR, but thought that would only be effective short range, and would not be too helpful at 65 km/h.

I saw the video pop up in my Youtube recommended, but didn't bother watching because I just assumed that any cars tested would be using LIDAR and thus would ignore the fake road just fine. I had no idea Tesla a) was still using basic cameras for this and b) actually had sophisticated enough "self driving" capabilities that this could be tested on them safely.
They tested a LiDAR rigged car, and it stopped just like you predicted. As of 2021, Tesla uses only cameras for FSD, and not even radar (which my stupid fine Toyota truck has).
They tested the idea safely by building the wall out of styrofoam, or at least that's what it looks like when it blows apart :)
Front-facing radar is the bare minimum needed to pass the test given (fake-road wall). Many vehicles use it for adaptive cruise control, and radar is even faster than either cameras or lidar for figuring out the range to an object. 1000 Hz measuring distance to an object is enough to find both the relative velocity and the acceleration of another object. This provides enough time to apply the brakes safely when approaching a vehicle or obstacle
LIDAR is even better, and also more compute intensive and expensive to install.
I think Tesla was very short-sighted in removing radar sensors, certainly. If they hadn’t, they could’ve spent more of their energy on making the FSD cars better instead of just making them sufficiently safe with insufficient sensors

Clearly we don't need lidar!

"But humans can do it with their eyes!"
The thing is, RADAR can see things humans can't. There was a whole article a while back about a Model X that avoided an otherwise unavoidable accident by bouncing radar under the car in front of it and seeing that car slam on the brakes.

The day I heard that was the day I realized he's a fucking idiot and I wanted nothing to do with his cars/tech.
Judging by how things have turned out...damn was that a good decision lmao
They pulled the RADAR from mine just before I took delivery, unbeknownst to me at the time. I received no sort of notification.

New Trump-Hitman challenge unlocked
Still think LIDAR is inferior to computer vision, Elon?
That was never in question, they just went with cameras because they're dirt cheap compared to lidar.

Wonderful news.
They sound like they’re perfect for red states
I am a bit disappointed to not see the Tesla crash into a real wall. I feel a bit click baited here.
Also, they prepared the polystyrene wall to break this cartoonishly, but still played on being surprised.
I’m a bit disappointed they painted identical to the actual road. Probably a lot of humans will get fooled by that one. We should send a challenge back: how looney toons can you get? Will something more cartoonish fool it? Will a different landscape fool it? How about drawing an oncoming train?

I would say that it's a good idea to paint more tunnels on walls, but then I remember how dumb human drivers are too
