It's "affordable" at $30k, but it has 1/2 the range of the Model 3 at around 130 miles, which I think tells you a lot. This technology is still at a price point where you need to make significant trade-offs between range and price. A new Honda Civic is something like $20k by comparison, and without the range anxiety.
Still, I see a lot more of the these Hyundai Ioniqs here in Amsterdam after they were released, particularly as workhorse vehicles like local taxis. Part of that's government incentives to use electric vehicles, European customers having lower range requirements, and that gas is still practically given away for free in the US compared to what it costs in the EU.
