Acceleration on losing traction?

Hi there, I have had a BMW c Evolution for a few years now and absolutely love it. However, I had a crash/dropped it yesterday and the accident has me wondering about what happened:

I was riding slowly with a pillion passenger; we were in a village affected by the flooding in Valencia, so there were large patches of mud visible on the road. As I approached a roundabout i felt the rear wheel lose traction. I should mention that one thing I love about the scooter is the dynamic throttle control, I rarely touch the brakes as I find the throttle sensitive and quite a strong deceleration when throttle closed. As the motor deceleration is on the rear wheel I seem to have developed the habit of only using the front brake if braking is required, I guess I figured at some point I am getting rear wheel braking anyway so why bother. This is relevant because first reaction is to close the throttle and ride out a situation like that, odd because as I say we were already easing slightly. However, the sensation and sound I had was that the bike actually continued, like the engine was pushing the rear wheel around, maybe even faster. I then applied front wheel brake, the front wheel stopped, but still the rear kept going so the bike sort of spun 90-140 degrees, I planted my foot during that spin but bike was already leaning and the rear kept going, so I dropped it. Fortunately no injuries but I feel particularly bad as carrying passenger.

I can't explain why the bike would have accelerated like that. Is it possible that a traction control system played up and rear wheel really did drive on? Obviously an application of the rear brake would have sorted it if it were the case but I'll never know.

In this type of situation, you should’ve been riding in the rain mode. I started off using the dynamic mode in the beginning and found it nice and fast but rather jerky so I just keep it for special occasions. I ride with the rain most of the time because it’s so smooth and easy and I seem to get less of that heavy whining sound also which I think might be something to do with the recharge of the battery system.. road mode is also very good. Eco mode is good but always I don’t know slowing you down when you don’t really want to slow down that much. I’d rather rather just coast up there with less force to stop. so once again, rain mode is my most comfortable riding mode and the other side play around with as I go.
