This is very evident on So.Cal freeways. As a salesperson I do a lot of driving and have been noticing a shitload of new Kias and Hyundais lately.
The two models I have driven still aren't as nice to drive as Japanese, but they will be there very soon. Design may take a bit longer though.
Their tires fuckin blow. I have shitty Hankook on my Toyota and Toyo on my Cube. Thinking about putting Toyos on the Toyota because they handle so nice.
