Oh my this place can get so particular (and kinda negative, eh ?) A crawling MS with AP has pretty decent vision, actually. At 2 kph or 50 cm / sec the radar and ultrasonics will probably know better than a human being could what's around. That's all I meant, I was approaching it from a "what if" challenge with existing hardware, not a requirement to drive beyond, as I said, a crawl.That wouldn't help. going slow doesn't help avoid the inability to see cross traffic. Entering an intersection slowly while blind is no safer than doing the same thing at normal speeds.
