Why No Overwing Exit On E170?

I recently just noticed that the E70 seems to be the only aircraft with only doors at the front and rear of the aircraft. Even the CRJ/ERJ have an overwing emergency exit. Why is that?

They don't need it to meet evacuation requirements and not having it saves weight.

I believe the certification requirements are emergency exits must be no father apart than 60 feet.

Considering the doors are certified as emergency exits, they are within the 60 foot limit so no over wing emergency exits are required.

The Existing exits serve the evacuation requirements for the capacity it carries,so not needed.

As everyone else has said, it isn't necessary. CRJs only have the over wing exits because they don't have rear service doors like the Ejets do. These double as emergency exits, hence no need for overwings.

Full size doors as others have mentioned. Having seen a few videos of evacuations off this aircraft (a couple in real world situations) they work very well.

190s don't meet the regulations without the overwing exits, so they have them.

Also the BAe146/Avro RJ series.

This link states that as of 1987, Exit Doors need only be "evenly spaced". New regulations being proposed would require exits to be at least 60 feet apart and within 30 feet of any passenger seat.:
