Not many. Elon said their plan was to produce 500k per year and they did less than 5% (15k) of that over the last year. Their installed production capacity is 125k.

The Ford Edsel is widely regarded as one of the greatest car flops of all time and it sold 60k cars per year for their 2-year production run.

The CyberTruck is a massively bigger flop than that.
