You’ve got to chill the hell out. Besides, we’re talking about Mars. They’ve already sent commercial parts. The problem is that they couldn’t afford to use more durable structural pieces. Yes, like Curiosity as you said. The wheels were shredded because they were extremely thin. If they had the mass budget for solid steel wheels, more powerful motors, and a larger power source to compensate, that’s that problem dealt with. Engineers are more clever than you seem to think.
