One thing you can never accuse Tai of is being shy about publicity for himself, and him being back in the GP a year after almost losing his life will undoubtedly generate headlines (at least in the short run). Id wager that more non speedway fans have heard about him than they have of Zmarzlik.
On recent form? He should not be near the GP. No title or even gp win since 2018, and his last three attempts have seen him finish 8th, 11th and 18th. Plus he won't have ridden competitively for the best part of 18 months by the time the 2026 season gets underway. Worth remembering 20 years ago, Tony Rickardsson had a completely unsatisfactory end to a successful world championship career as well
If he proves us wrong and has a strong season, with a top 6 finish and one or two wins, brilliant. But the odds are heavily stacked against him.
