Yes, I believe they have an L2 but are working towards and L4. Google is still going straight for L5, which is the only case where you can fully remove the steering wheel. It's a huge bed, and a bit silly, honestly. I feel like at this point, they've definitely got L4 down.
L4 basically says the car can drive itself without attention in most cases. Driver only needs to take over in extreme cases where the computer can't figure it out (something on the road blocking, sever weather, super abnormal situation).
