In the past this feature makes possible to show your position live using any browser. The URL sent to recipient just points to map with a car marked on it, and moving.
However I noticed sometimes (quite often) the URL caused to open destination area map, without even calculated route. Something was broken. Recently I didn't check this feature, so don't know if it works.

However I found another issue while using this functionality. There is (was) no option to change the language of the message. I can understand difficulties determining language in case of some communication channels (like e-mail in .com domain). But web page showing route's information to a recipient:
a) can open with language depending on browser localization
b) should have an option to change the language
BTW in case of sending ETA via SMS, it is possible to determine the language by phone number prefix.
Probably other channels offer some abilities too.

with regards

Yes. That's the point.
I live in Czech Republic having my mobile phone configured for Czech language. Sometimes I go meet my family in Poland. What's the point to send Czech message to Polish?

BTW you can easily change language of message shown on web page by simply modify part of URL (there is part defining the language). But most of people are not able to do that. Why should they do, if it have to be done by the system? In case of Web browser, language can be selected automatically. There is no magic at all.

Usually I'm sending ETA via email.
Single SMS might be 160 chars long max, but nowadays mobile networks supports longer sms, by splitting them into smaller ones and joining back at the end. However it's up to Waze to not send longer messages. URLs itself are not long enough to make problems.

I'm not sure you are confirming my complaint or arguing against
But actually you are not right. It's true you cannot change the language using available UI. But you can modify URL. Note, sent message contains shorter version of URL. If you open it in browser, the URL is redirected to full version with parameters which look like this:
In this particular case, /cs/ defines language. You can change it to any supported one: en, pl, fr, it and more. It will show page in selected language.
So only thing to do is to provide language selector for an user, and select proper language based on browser locales.

Things like this would be in the Waze help pages, not the forum.

Here is the page on sharing ETA:

I've moved your question from the feedback thread about Waze 4.9 for Android to a recent thread where the same question was asked.
