That last sentence tells me that a few people on this forum don't quite comprehend the auto industry landscape.
Toyota has been anything but asleep at the design studio. Toytoa has been pushing the design envelope with regards to hybrids, turbo-gasoline's, hydrogen fuel cell, electric, ect. They, as well as other foreign auto makers, have consistently eaten away at the market share of the big 3 in all vehicle segments, except certain types of trucks. The only reason the big 3 still have a dominant hold within the 1/2 and 3/4 ton segments is because of protective trade policies (chicken tax on foreign trucks) and because the big 3 have poured most of their R&D and focus into trucks, pretty much at the sacrifice of most of their other product lines.
GM is pledging to ditch all internal combustion engines by 2035; we might see similar moves by Ford and Ram. Between those corporate decisions and increasing pressure on OEM's to ditch gas-guzzling designs, it remains to be seen if the big 3's truck cash cow will survive much beyond the next 10 years.
Toyota, on the other hand, is doing just fine. Their main focus is on selling reliable cars and CUV's; their truck business (at least within North America) is merely a tangential focus. Toyota seems content to move at a gradual pace with their truck designs and updates. And based on the last few years of sales for the 4runner and Tundra (both of which are constantly belittled for being "outdated"), it would seem Toyota buyers have been content as well. Toyota has a small (relatively speaking) but loyal consumer base for its trucks...they've never seem interested in trying to convert masses of marginal buyers in the same way that the big 3 have.
