Perplexity.ai teaches about highways

kurumi:
A ChatGPT alternative is perplexity.ai, and right away I learned a lot about Connecticut highways! These are some serious hallucinations.


--- Quote from: https://www.perplexity.ai/search/c7063512-340a-461f-aeb4-33c48a609a32?s=u ---Connecticut has used a majority of the available numbers for its highways, but there are a few that have not been used or are not currently in use. Here are some examples:


* Odd Numbers above 199: Connecticut has not used odd numbers above 199 for its state routes[2]. The highest odd-numbered state route in Connecticut is Route 199, which runs from Pomfret to the Massachusetts state line[2].
* Even Numbers above 218: Similarly, even numbers above 218 have not been used for state routes in Connecticut[2]. The highest even-numbered state route in Connecticut is Route 218, which runs from Windsor to Bloomfield[2].
* Three-Digit Numbers above 399: Connecticut has not used three-digit numbers above 399 for its state routes[2]. The highest three-digit state route in Connecticut is Route 399, which runs from Route 189 in Bloomfield to Route 218 in Windsor[2].
* Four-Digit Numbers: Connecticut does not have any four-digit state route numbers[2]. Four-digit route numbers are typically used for local or county roads in other states.
* Exit Numbers above 100: With the ongoing exit renumbering project, Connecticut will be using exit numbers based on mile markers, which means that exit numbers above 100 will not be used[5]. The highest exit number in Connecticut is currently Exit 130 on I-95 in Stratford[5].

vdeane:
I guess the number 399 is neither even nor odd.

epzik8:
Yeah, exit 130 being in the western part of the state is horrible.

pderocco:
Switching from consecutive numbered exits to mileage based numbered exits spreads them out, requiring larger numbers. The last exit on I-95 will probably switch from 93 to 203. Of course, that could have been the stupidity of the writer at the Hartford Courant; I couldn't tell because of the paywall.
