Other than the F-117 Nighthawk,some vehicles I found,which don't allow the air to remain at frontal area for more than a 'blink' are:
1995 Dodge Viper Defender show car
2005 Pagani Zonda
2006 Daihatsu UFE-III concept
2009 Nissan Z-car
2011 Jaguar C-X75 concept
2011 Nissan JUKE
2011 Land Rover Range Rover Evoque
2011 LEXUS LFA
2012 Porsche 911 Carrera S
2012 McLaren MP4-12C
2013 Porsche Cayman S
2013 SRT Viper
2015 Ferrari LaFerrari
No doubt,we should expect immediate flow separation downstream of Cybertruck's roof apex,however,the locked-vortex produced there,may produce the 'missing' contour which allows for rapid,spatial reattachment of the inviscid 'sound' flow outside it.I suspect that this is the case for every aspect of Cybertruck's body.
