May U.S. Mirai sales per IEVS: 162 (579 YTD). The IEVS article has a mistake and says 305 YTD, which was the total at the end of March IIRR. Of note, the Clarity FCEV saw its leases jump to 119 in May (previous high 42 in January), so I think the word is spreading that it's a better car than the Mirai.

The 'best' is the enemy of 'good enough'. Copper shot, not Silver bullets.
