How fast & sharp of a turn can you do on your bike
Tell us (1) Type of bike e.g. hybrid, road, mtn (2) tire width (3) turning speed (4) turn angle. We'll use angles to give an idea rather than give exact measurments since turns on bikes are curved.
I was practicing sharp turns to test my handling skills. Today I did a "90 degree turn" at 20 MPH on a T intersection. My turn was not perfect. While I remained in the correct lane after my turn, I was close to the middle of the intersection and near the opposing traffic lane. I did this at an empty, private street with 0 traffic. I was riding a hybrid bike with 28c tires, and 20 MPH at a T intersection.
What about you guys?

I can't put a number on it, but I found a sharpness limit on my mountain commuter.
I was flying to make a light, and cut hard with my inside pedal down. The pedal hit the pavement, and my path looked like the "slippery when wet" sign for a few seconds. I managed to stay upright. At the next light, a lady in a car looked over with buggy eyes and mouthed "Wow!". I smiled, shrugged and rode on.
But I learned to pick up the inside pedal.

Turn angle is meaningless. School buses can turn 90 degrees at 60mph with sufficient radius.
Here's a thread that discusses turning.

I've done that on my mountain bike on a 4'~ wide bike path. Quite often too waiting for my kids to catch up or turning around at a dead end. I've made mulitple 360's around my kids bike goofing off in the driveway goin at a decent speed giving the circumstances. nuttn special, but I do try to push the limit when possible just to see what the limit is.

I don't really know that I could measure it. I do know when I have exceeded my, the bikes, the tires, or conditions ability to hold it though.

Had a pair of 90s sneak up on me while racing a buddy along the M6 trail, slowed down to a comfortable speed before I hit them. While going through the second I looked at the speedo and saw that I was doing 23mph. I stayed on the pavement, which is about 8ft wide there, thought it was good for going into the bends on the wrong side.
