I think they are minimum 3 years away from anything exciting beta.. but the localization, mapping, and visualization are not the reason. I don&amp;#x27;t think LIDAR would contribute substantially to improvement.&lt;p&gt;The fundamental flaws are in the decision-making being based upon 10-30 second feature memory, ignoring features outright, and only depending on visible road features instead of persisted map data.&lt;p&gt;For instance, near my house there&amp;#x27;s an intersection where it will try to use a turn-only lane with a red arrow when it&amp;#x27;s trying to go straight thru a light. 100% of the time. Even if I&amp;#x27;m in the correct lane with no traffic around.&lt;p&gt;That&amp;#x27;s because the turn arrow on the ground is worn off. It is not a perception problem, it is&lt;p&gt;a) ignoring the obvious red turn arrow signal&amp;#x27;s significance for lane selection deliberately
b) makes no attempt to persist or consult map data for &amp;#x27;which lanes go where&amp;#x27;
c) it completely disregards painted lines on the ground in the &amp;quot;no drive here&amp;quot; striping.&lt;p&gt;Also one block from my house, FSD will stay still indefinitely waiting for trash cans (displayed as trash cans) to clear the leftmost lane so that it will turn left.&lt;p&gt;None of the failures I encounter are due to lack of perception.</text></comment>

They have been working on this problem the longest and they aren&amp;#x27;t even confident enough to produce a product with it. Google is probably the leader in AI and AI research. They are also the leader in data and mapping. They have billions of cash to play with. Yet it seem like they haven&amp;#x27;t gotten any closer at solving this problem as well.&lt;p&gt;They are just going about it better but not trying to selling it.&lt;p&gt;Any reason why everyone seems to be stuck on this problem?</text></comment>
