In EY, you don’t date by car usually. You usually meet in a hotel lobby – a very public place. You usually don’t go for a walk on the first date, and if you do, it’s in a very public area.
And, uh, personally, I don’t talk about sensitive and frivolous topics on dates.
If you’re a tznius person and you go out with tznius people, there shouldn’t be any problems.
I do agree that it would be great to have parents who could arrange things for me, and the chassidish way of doing things is great – but, it can only work if you’re from that type of society. There is a reason why different societies (within the Orthodox world) have different ways of dating.
Sociology is a complicated thing. When things are done a certain way in one society but not in another, it is usually because there are other things that are done in that society that make this thing possible in that society and not in others.
Someone from a Yeshivish society or a Modern Orthodox society can’t necessarily choose to do something the way it is done in Chassidish society and expect it to work.
