Overhead joins can be dangerous where two aircraft are joining at a similar time.
Exactly, but they are used at the very time when the circuit is busy and (if ATC) when ATC is unable to cope. Then they just send everybody into the overhead. It is a dangerous place to be.
Remind me again how many mid-airs have happened through OHJs in the last 5 years or so?
It can be stressful, but so can joining at any point in the circuit.
